How do I apply an overpayment from last year to this year's taxes?

To enter, change or delete a refund from the prior year applied to this years taxes (Federal, State, Local) -

• Click on Federal Taxes (Personal using Home and Business)
• Click on Deductions and Credits
• Click on I'll choose what I work on (if shown)
• Scroll down to Estimates and Other Taxes Paid
• On Other Income Taxes, click on the start or update button

On the next screen select the options under 2017 Refund Applied to 2018

Or enter refund applied to this year in the Search box located in the upper right of the program screen.  Click on Jump to refund applied to this year

Thanks for the tip on how to report a Federal overpayment from 2019 that was applied to 2020.
