I found that this affliction crashes TurboTax Premier for 2019, 2020, and 2021. I am not having problems with older versions. I tried the uninstall/reinstall procedure in the link for the 2020 software and it seems to work...for now. I now need to locate my install disks for 2019 and 2021 to see if they are salvageable as well.
This was very disruptive to my family's returns. TurboTax 2021 worked fine in February/March 2021, but was unusable in April. Before I found this thread, I had to use one of the IRS Freefile services for the last return (that person's income was low enough to qualify for Freefile).
Poor support by Intuit. I may switch back to H&R Block software next year.
