I did get a response after sending my diagnostic file and they came back saying there was no issue. Since I didn't feel comfortable filing my taxes through TurboTax still, I had them done by another company. The results from that return were the same as TurboTax, so that is good.
HOWEVER, what I learned is that because we itemized our deductions on our Federal Taxes, we have the choice to itemize Minnesota deductions or not per the SALT program. In my case, it was better not to itemize and to take the standard deduction. TurboTax software never gave me that option and defaulted to itemizing, which lowered my refund. I would hope that the software would default to the biggest refund, or at least bring it to my attention during the review process, but it didn't. So anybody else in my situation is also losing out on additional tax refund dollars, which is $600 in my case. I now plan to see if this hurt me in my prior returns, and file an amended return if necessary. The only reason I became aware of this situation is because I missed entering my property tax deduction at first. If I hadn't done that, I would never have known that I had the option to leave it, or some other deduction, off in order to maximize the state refund.
I do want to mention that on my first call with TurboTax they referenced the SALT program and told me to leave the property taxes off my return, but I didn't feel confident about why I was doing that.
I hope this helps someone else who may be in this situation.
