Update. I've spent about 5 hours on the phone with TurboTax (I didn't pay extra for Live) and they finally sent it to a developer to check into. The first agent and their manager tried to get me to just not enter the amount of property taxes I paid to avoid the issue of my MN refund going down by $600. I should be able to enter my property taxes paid and trust that TurboTax is calculating correctly. Also, I want to make sure others don't get penalized without realizing it. I'll post another update when this question is resolved.
