Time Machine not working after Mojave Update

Hello,

I have a Mid 2014 Macbook Pro - I am SO satisfied with this laptop. It has done great things for me and I plan on replacing it with a new version once its life is over.

The other day, I finally upgraded to Mojave from Yosemite 10.10 - I had some compatibility issues with programs I was using and Mojave seemed to be the best fit. I am overall very satisfied with the update, but CANNOT get Time Machine to work.

Each time I try to back up, it says "Backing up: Zero KB out of 197GB" and just stays there. It has stayed there for HOURS. I have reformatted and repaired my drive, I have gone into preferences and deleted the "com.Apple.TimeMachine..." file, I have rebooted my machine countless times. I do not understand why this isn't working, and I am worried that if my computer dies, I won't have any data because I reformatted my drive. any suggestions?

Thanks for your help!

The drive itself could be suspect. Try a different drive and compare the results.

Strange. Your TM picture does not have the lock underneath left....

Open TM preferences as in your picture,

then "Select Disk",

make sure that is is the "selected disk" (on top) from the disk list that shows.
