If you are residents of NJ, you don't file PA as long as you filed REV-419 with your employer. Since you don't have PA wages, there is nothing to be done. Your employer handled it.
The Reciprocal Personal Income Tax Agreement between Pennsylvania and New Jersey means compensation paid to New Jersey residents employed in Pennsylvania is not subject to Pennsylvania income tax. Therefore, you cannot claim a credit on Schedule NJ-COJ for taxes paid to Pennsylvania on those earnings.
