Corrected W-2
Menu Path: Income > Common Income > Wages (W-2)
Enter on the Wages (Form W-2) screen as a regular W-2. At the bottom of the screen, answer Yes to the question that asks if this a corrected W-2 from your employer.
If your corrected W-2 is a complete W-2 just enter the corrected W-2, don't enter the original W-2. If your corrected W-2 only shows the changes made to the original W-2, then enter the original W-2 and then enter the changes shown on the corrected W-2.
