Do I need to mail my out-of state W-2s to PA as a non resident grad student?
I am a full time grad student in PA. This is my first time completing a PA state return. I am a resident of another state and have W-2s from the state I am a resident of, as well as one from PA. In completing my PA (nonresident) state return on TurboTax, it stated that I need to mail-in a copies of my non PA W-2s and I had to complete a statement of explanation. I am ready to submit my taxes but don't have any additional information about mailing in my physical W-2s to PA. How do I proceed with this?
