TurboTax 2020 won't open on Mac Big Sur 11.2

Until TurboTax provides a working update, try something I found on discssions.apple.com: TurboTax will still run on Mojave. I have an external SanDisk drive with Mojave installed on it, so I restart my Mac from this drive, and TurboTax runs as smoothly as before. My Mac Hard Disk and its Documents folder with my TurboTax files (as well as Quickbooks, Excel, etc.) is still accessible. When I'm done working on TT, I just restart from my internal drive as I would normally. Annoying work-around, but it does work.

You can download Mojave from Apple and install on your external drive:
