@BillM223
BillM223, I have already filed my taxes elsewhere for this year prior to the fix. However, I went back and tried the IN state annualization again in TurboTax, and from what I can see, it does appear to be fixed. It asked for my quarterly IN AGIs, and it asked for my quarterly IN credits. After inputting these values, my IN state tax penalty was removed, as expected. However, since I am not paying to file with TurboTax this year, I can't confirm all of the individual calculations on the IN form IT-2210A. However, the parts I am able to confirm without paying appear to be working correctly now.
