<prompt> Human: I received my W-2 and thought it a good idea to go ahead and start my taxes since I already had all the paperwork I needed to complete them. I used TurboTax and got everything filed. Everything went smoothly and had no problems whatsoever. So about a day after I filed my taxes, I received an email saying there was a mistake on my W-2 regarding something in Box 13 that had not been checked previously and that it has been fixed. But, even though the Retirement Plan box hasnt been checked on the one I submitted, Box 12a still has the amount I contributed to the 401k and that part was filed correctly. I cant go back and fix the mistake because theyve already been filed and are still pending. Should I be worried about this?  <response>: File an amended tax form with the correct tax information.
