The Form 1040-X for amending a 2025 federal tax return is estimated to be available in TurboTax on 02/25/2026
You will have to wait for the IRS to either Accept or Reject your filed federal tax return.
If the return is rejected you can make the necessary changes and e-file again.
If the return is accepted you will have to amend your original tax return. 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.

The amendment form 1040X will only be available in TurboTax after 2/25/2026.
If you are expecting a refund, we recommend that you wait to amend until after the IRS has processed your original return and you have received your refund.
