You can always go back to the beginning of the tax filing experience from the Tax Home page. Under "Basic Info", click the "Review" button to edit information from the beginning of the return. You can delete any information already entered and re-enter the correct information there.
If you have added any forms that you would like to delete or remove, you can follow these steps.
- Enter the section via Tax Home you have added the form in (e.g. "Income")
- Select the sub-section via the menu there (e.g. "Wages (W-2)")
- Click the icon with three circles next to the form you would like to delete
- Select "Delete" from the menu there
All information in the tax filing experience is auto-updated as you enter, so anything you delete or correct will automatically be saved.
