This appears to be just one more way Intuit is letting down Desktop users and supporters. This has never happened to me in 24 years until this quarter on the 2020 version and some older versions. All you can do is manually figure the amounts, override the numbers and enter them, and the form will populate the corrected tax amounts. Sad Intuit has become so unreliable. They are just trying to force everyone to use their more expensive online version.
