where do i input the overpayments applied from the prior year tax return (i did not use turbo tax) and where do i input the extension payments? thank you.

To enter last year's refund you applied to this year.

Federal (Personal for Home & Business)

Deductions and Credits

Then scroll way down to Estimates and Other Taxes Paid

Other Income Taxes - Click the Start or Revisit

Next page scroll down to 2023 Refund Applied to 2024

Click Start or Update by the tax you applied

To enter the amount you paid with an extension (including state extension)  go to

Federal Taxes (or Personal for desktop H&B version)

Deductions and Credits

Then scroll way down to Estimates and Other Taxes Paid

Other Income Taxes - Click the Start or Update button

Next page second section Payments with Extension

Either Visit All or Click Start or Update by the extension you paid

Pay attention to which year you are entering for a State Extension payment.  A prior year state extension payment is also deductible on the federal return so be sure to enter it here.

To get the amount paid on a state extension to show up on the state return……

When you are done updating your federal return, you need to transfer the new federal information by going back through the state tab and the state return. Nothing will change until you transfer the fed info to the state again.
