Without looking at your return, it's hard to tell what's going on.
All the error messages about Minnesota standard/itemized deductions seem to relate to the 2019 return. I think if there was a problem for 2020 there would be messages about that as well.
I suggest contacting a TurboTax. Ask for a CPA, Enrolled Agent or Tax Attorney. Tell them to pull a sanitized "diagnostic" copy of your tax return. This is a copy where personal identifying information is removed. The expert can look at how the numbers are flowing onto your return.
