I guess you'll have to mail it in if the system won't let you e-file. If your W-2 shows NY income, you might want to include a note explaining that you never actually worked in New York State, nor are you a telecommuter for an NY employer, and thus NY taxes should not have been withheld. On the PA return I would not say that you made money in NY, since in fact you didn't.
