Hi, I noticed something was wrong with my W-2 for a job, it had an extra state listed in box 15 and an extra stage wage for that state in box 16. I contacted my employer and they provided me with a W-2c which corrects the extra state. I have not actually filed my taxes yet, so do I need to attach the W-2c anywhere, or can I simply put in the information thats correct and then file that?
