After you file

You can’t add another W-2 (nor another type of tax document: 1099, 1098, etc.) if you have already filed your tax return.

The IRS may either Accept or Reject your filed federal tax return.

If the return is rejected you can make the necessary changes and e-file again.

Enter your W-2 by:

1. Open or continue your return.
2. Go to the W-2 screen under Wages & Income.  Select Work on my W-2 and Continue.  (or you can type "w2" in the Search box; and click on "jump to w2" link).
   If you've already entered a W-2 or need to add another one, select Add a W-2.
3. Enter your Employer Identification Number (EIN) from Box b on your W-2.  If your W-2 can be imported, you'll come to the Great news! We can automatically import your W-2 info screen. Answer the questions to complete your import.
4. If TurboTax doesn't recognize your EIN you can use the TurboTax mobile app to snap a photo of your W-2, upload it from your computer, or fill it in yourself.

TurboTax FAQ: How do import or enter my W2?

If the return is accepted you will have to amend your original tax return using Form 1040-X.  If you e-filed your original return, then you can go back online to make the necessary changes and then e-file the amended return.

However, if you paper-filed (mailed) your original return, you will need to paper-file (mail) your amended 

return.

The IRS may take up to 20 weeks or longer to process an amended tax return.

Also, before you start to amend the tax return, you should wait for the original tax refund to be received (or the taxes due to be paid).

For more information, please see TurboTax FAQ: How do I amend my federal tax return for this year?  

The tentative date that the 1040-X form to amend your original tax return may be 2/19/26.
