Have tried reinstalling, but no joy. BTW, the amazon website doesn't list the 2020 version of turbo tax as being supported with Big Sur. Interesting.
Intuits tech support isn't even honest enough to admit that there's an issue. Many others have reported that they have been kept on the phone for over 4 hours, while their "tech support" fumbles around to try to find an answer, which in the end they never do. Under these conditions I think it's best to simply get a refund.
