Mark that you earned income in another state.
Prepare a NY nonresident return first declaring your wages earned in NY. Then prepare a PA resident return showing ALL income regardless of where earned. Be sure the PA return contains a Schedule G giving you credit for taxes paid to the "other" state. If you had little income other than your NY wages, you may show a zero balance on your PA return as NY has a higher tax rate.
Any unused portion of taxes paid to NY may be used to offset your local earned income tax that you also must file, TurboTax will not help you with the local.
