MacOS Big Sur Compatibility with TurboTax for Mac 2020

I requested a refund per instructions on Turbotax/Intuit website. They have an odd guaranty; one has to submit a request and then in 3 to 5 business days they will tell you whether they "approve" your request or not. Like they're doing *me* a favor? I submitted the refund request last week, so I expect the reply any moment now. I purchased TT Premier direct from TT/Intuit, not a 3rd party, so the refund request should be straightforward (e.g., TT can just void the license key).

Try using the demo version of Pacifist to install Turbotax.

I ran the latest upgrade on my Mac and it resolved the issue

Big Sur 11.1

last update was a software update they released with a script utility that did the trick for me

I’m having the same problem. I downloaded Turbo Tax home and business 2020. It let me transfer my 2019‘s over that I imported from my HP to my Mac. It let me enter my schedule C but would not let me enter any information on my 1099’s (I could not key any number). I called TurboTax and a agent screen shared with me. She also could not solve my issue, told me there was something wrong with my download, to delete and download it again and it still didn’t work. Apple help me with that download. Does anyone at Apple know why?

I fully agree that it is unneeded and WILL cause problems. Just to explain further, the Mac has its own built in protection as part of the operating system. Further, with the current operating systems, when you open Disk utility and view your hard drive, you now see two: Macintosh HD and Macintosh HD-Data. the first one is where all of Apple's apps and files are placed. It is read only, which means that no virus can be installed there. The operating system can not be modified or affected. Period! The files and apps you install or create are placed in the second part. This is as good as it can get and there are no problems caused as with all of the antivirus apps.

There is no reason to ever install or run any 3rd party "cleaning", "optimizing", "speed-up", anti-virus, VPN or security apps on your Mac.  This user tip describes what you need to know and do in order to protect your Mac: Effective defenses against malware and other threats - Apple Community   

That being said you've installed Cylance which is totally unnecessary for Macs. It should be uninstalled according to the developer's instructions. Then you can check to see if you've removed all of the supporting files by downloading and running Find Any File to search for any files with the application's name  and the developer's name in the file name.  For Cylance software you'd do the following search(es): 

1 - Name contains cylance

Any files that are found can be dragged from the search results window to the Desktop or Trash bin in the Dock for deletion.

FAF can search areas that Spotlight can't like invisible folders, system folders and packages.  

Here's some food for thought:

Google is known to "phone home" with users data as was found out with this new Google Photos service:  Google Photos may be free — but there's still a cost.

If you don't like Safari give Firefox a try.  It's much more secure and safe.

Thanks. What is weird is that after install and not working, and TurboTax customer service being closed already, I let the computer sit over night. The next morning I had notifications that updates to TurboTax were complete, and it worked!

I spent 5+ hours on the phone yesterday with TurboTax support. Went through 4 different support techs. Followed all instructions for uninstall/reinstall and still nothing. I'm running Big Sur 11.2 and it's the newest update.

Interesting. Before I received the “we’ve hit a snag” message and everything crashed I noticed that Schedule E wasn’t available on TT Premier and also that data I had entered earlier in the program seemed to have disappeared. Something is definitely jacked up. Also, 2019’s data had disappeared.

I have spent 6 hours with Turbo Tax support and they have no clue how to address and fix the program. They even tried to download a new tax program and it has the same result. It Doesn't WorK!! See my other comment for Apple Support suggestion>

Good Luck!!

After most of a day and four different techs, TT support essentially gave up and did send me a refund link. The link requires an order number as proof of purchase. So if you bought the CD from a third party and not directly from Intuit you’re out of luck.

I have tried to install TurboTax over 10 times with no positive results. I may have to use the online version.

I'm not showing a new upgrade, I'm on Big Sur 11.1. What are you on?

Amen to that. Turbotax 2020 will not run on my iMac 2020 - it's just a few months old, running Big Sur 11.2, and I have very few 3rd party apps installed.
