I downloaded TurboTax to file 2020 taxes for 2 states. It crashed when importing the 2019 returns but then accepted them when I tried again. I downloaded the state returns for 2 states. When I get to the page to enter the W-2 details by inputting the Employer ID, it crashes. I have probably tried 20 times.
I am on a Mac if that matters
It's doing the exact thing for me too. 2020 Turbotax Premier for Mac. Crashes when trying to enter W2 info for my employer. If I skip that W2 for now and enter my wife's W2 info that works, but then if I try to enter a new W2 for my employer, it crashes after entering the Employer's FED ID number...
