After finishing and printing fed tax return it included Schedule 1 but it is blank except line 1 shows $0. Why did it print? Do I need to send it? Note: I have a W2 for NJ withholding and a separate W2 for PA withholding. I live in NJ and work in PA so the PA W2 shows $0 fed wages.
It sounds to me as if you entered a 1099-G for a state refund and the program determined that the refund was non-taxable.
Yes, you should include Schedule 1 if line 8 on your 1040 (which is where the Schedule 1 is reported on your 1040) is also 0.
It will make clear what the program did. (You entered the State Refund, the program determined it was not taxable)
If you did NOT enter a state refund, please continue your question and supply more details if possible.
