I did my return last year with TurboTax Premier 2020.
I purchased TurboTax Premier 2021 this year, and tried to start a new return by transferring from last year's tax2020 file. It showed a "Nothing happens" screen, and then nothing happens.
I tried starting a brand new 2021 return from scratch. After ~30 minutes in, I saved the return, exited the program, started it up again, tried to load the return I was working on, and got a "tax file is corrupt."
