I am amending 2021 return. The only change is 1099-R was corrected with an increase by $20 to line 2a - taxable amount. TurboTax is supposed to update line 5b on 1040 with the new amount, but instead it adds the old amount and the new amount. I traced the error to 1099-R summary page. I did all the usual troubleshooting and verified entering 1099-R correctly. How can this be addressed?
