Look at the PA Schedule W-2S form from your PA return. You must mail in anything listed under part B.
From the instructions
Part B Instructions: List each source of income received during the taxable year on a form or statement other than a federal Form W-2. Enter each payer’s name. List the payment type that most closely describes the source of your non-employee compensation. Enter the amount of other compensation that you earned. If the form or statement
does not have separately stated amounts, enter the amount shown in both federal and PA columns.
IMPORTANT: You must submit a copy of each form and statement that you list in Part B, whether or not the payer withheld any PA income tax and regardless of whether or not the income was taxable in PA. CAUTION: The federal and Pennsylvania (state) wages may be different in Part A and Part B.
