Are you trying to amend your return? If so, after you start the amend process you can go back and edit the W2. Be sure you started the amend process first and the balance due or refund has reset to $0.
When it does go to Income>>then select the W-2 that you received the correction for and then just edit the numbers that were corrected.
Basically use the old W-2 and change the corrected entries.
