Hi,
1) Sign into TurboTax Online.
2) Continue your return by click Taxes > Tax Timeline > Take me to my Return.
3) Search for W-2 (upper- or lower-case, with or without the dash).
4) Click the "Jump to W-2" link in the search results.
5) We'll take you to a screen where you can edit or delete the W-2's you have already entered. (screenshots attached)
If you are unable to edit the fields on your W-2, I recommend deleting the W-2 and entering it manually.
