You can change or delete your W-2 info if you haven't filed your taxes yet.
In TurboTax Online or CD/Download:
- Open your return by selecting Take me to my return.
- From the top menu, select Search and type-in W-2.
- Select the Jump to link in the search results.
- On the Here's your W-2 info screen, select Edit next to the W-2 you want to change.
In the TurboTax Mobile App:
- Open your return by selecting Take me to my return.
- Select the menu button in the upper left-hand corner and choose Federal Taxes.
- Select Income and Expenses.
- From here, you will see Your income and expenses.
- Go to Wages and Salaries, select the three dots next to the person whose W-2 you'd like to edit.
- Select Edit to make your changes.
If you already e-filed, wait until your return is either accepted or rejected.
- If rejected, you can edit the W-2 as instructed above before resubmitting or paper-filing your return.
- If accepted (or if you already paper-filed), you'll probably need to amend your return if the edits you're making will cause your taxes to change.
