Thanks for your explanation @Mike9241 ! In order to get back the amount I lost to federal and state withholdings it looks like I would need to update box 1 with the accurate amount that was paid to me. However if my company didn't make that update in box 1 in the W2C am I allowed to make that update myself in my filings or can I only make changes where updates have been made to my W2C and later have to do a 1341 next year?
