TurboTax Tax Payment Worksheet double counted federal tax payments on line 1 and again on line 6. TurboTax applied a 2023 tax (refund) over-payment as the first (04/15/24) estimated tax payment on line 1. TurboTax again applied the same amount as "Overpayments applied to 2024" (line 6). Thus, (line 8), Totals of line 1 through 7, includes the same entry counted twice. This error results to an incorrect entry on line 26 on form 1040-SR.
The logical correction seems to be to apply the 2023 over-payment only to line 6 and not line 1 on the work sheet.
This occurred with the latest TurboTax updated version on 3/30/2025.
I discovered this TurboTax glitch after receiving (and investigating) a 2024 return notice from the IRS dated 21 April 2025.
How can I compensate for this error in the TurboTax 2024 file when the information is transferred upon starting the 2025 return next year?
