I posted a similar message on the TT mint board. The errors go even deeper. If you have a federal tax refund from 2020 that you applied to your 2021 taxes on the Tax Payments Worksheet, that amount is not picked up by TT's form as 'taxes paid'. Forms 2210 and 2210AI and Tax Payments Worksheet are not in sync. As you stated, lines 10(a) and 11(a) on the 2201 are in error... in addition to the error referencing line 27 from 2210AI.
