I ran into the same problem. Sat with customer support for a few hours. It comes down to doing a deep clean of the installed TT and re-installing. For that, customer service suggested https://freemacsoft.net/appcleaner/ which worked out really well. Just remember to only delete files related to affected year and not the old year's turbotax. Then go ahead and re-install.
When it opened, there was a window saying a snag was hit, as recommended elsewhere, I ignored that window and did NOT press send, as was suggested elsewhere. Everything is working fine for now.
