Similar issue, I owe penalty for MN and TT asked if I wanted to annualize my MN income to try and reduce the amount which I said no since it tells you that you cannot electronically file if you annualize your income. After buying the state electronic filing TT rejects my return saying I used the Underpayment Statement (which TT did some calculation on and filled in M15 line 22) and have to mail my return. I can't override what it did.
Obviously need a refund of the state filing fee and very unhappy that it looks like I may need to mail my return.
TT fix your programing error!
