I checked for updates in Turbo Tax on 2/13/2021 and downloaded the 2/10/2021 update. That update fixed my issues. After downloading the update I opened Turbo Tax and walked through the Minnesota tax return from the beginning. I no longer saw the screen that automatically checked the AMT option. Instead, I was asked if I ever claimed MN AMT in the past. I chose 'No' and was able to complete my tax return.
