How do I add an overpayment of estimated federal taxes to my 2025 refund?

[Cincode]

With the increase in the standard deduction and a lower income, estimated tax was not necessary. I am a single retiree with All 1099 income.

you should be entering your estimated tax payments under Deductions & Credits / Estimated Taxes and Other Taxes Paid section and it will be reflected on line 26 of your 1040.

Done! Thank you for your help.
