If you have filed the 2025 tax return and it has been accepted by the IRS then you will have to amend the tax return to add the interest.
The Form 1040-X for amending a 2025 federal tax return is estimated to be available in TurboTax on 02/25/2026
An amended return, Form 1040-X, can only be printed and mailed to the IRS if the original tax return was not e-filed. The IRS will take up to 20 weeks or longer to process an amended tax return.
Before starting to amend the tax return, wait for the tax refund to be received or the taxes due to be paid and processed by the IRS.
