It would greatly depend on weather you have filed it yet.
If you have not filed your return you can follow these steps to update or change your W-2:
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. If you are unable to edit the fields on your W-2, I recommend deleting the W-2 and entering it manually.
