If you have already filed, your return will most likely get
rejected if your Social Security number and last name do not match what
the IRS has on their records.
If you have NOT filed yet, follow these steps to fix the Social Security number:
- Log into your return and click orange Take me to my return button
- Click Personal Info tab and then Edit next to your name (or the name of person that needs a change) and correct social there
