The Form 1040-X for amending a 2025 federal tax return is estimated to be finalized and available in TurboTax on 02/19/2026
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.
See this TurboTax support FAQ for amending a current year tax return - https://ttlc.intuit.com/turbotax-support/en-us/help-article/tax-return/amend-federal-tax-return-current-year/L7eS6o1qh_US_en_US?uid=lfunevhk
You won't be able to file an amendment, until your tax return is fully processed and you receive your refund or your balance due is deducted from your account. In addition, the 1040X used to amend your tax return won't be ready for a few weeks.
