2. Select “Amend a filed return” under "Need to Amend a Filed Return?"
3. Select "Amend" for the return you want to amend (if it is not an option select "Find a Tax File")

If you are amending your 2024 tax return and you filed your original 2024 tax return in TurboTax you will be able to e-file your amended return. ‌ There are some circumstances where you will be unable to e-file your amended 2024 return and you will have to mail it in. TurboTax will tell you if it has to be mailed.

If you're amending your return for 2023 or earlier, you need to print and mail your amended return. Follow these instructions to amend a prior-year return.

You can use this IRS tool to determine if you should amend your tax return, click here and select "Begin" to enter your information. It will ask you questions about your issue.

Three weeks after mailing your amendment, you can start tracking it at Where's My Amended Return? on IRS.gov.

Some things to keep in mind:

• You must wait until your original return has been accepted to amend it.
• Amend only if you need to make a change to a return you have already filed. 
• Wait until you get your refund or have paid your taxes. Have a copy of your original return at your side before you start. And be sure you use the correct year’s software of TurboTax.
• You must file a separate Form 1040-X for each tax return you are amending.
• Amended returns can take more than three months for the IRS to process.
• Gather your original tax return and any new documents needed to prepare your amended return.
• Print a copy of your return that you are amending and have it ready to refer to. 
• Use the same TurboTax account you used to file your original return. 
• Be sure to only make changes to the areas of your return that need amending.
