I earned all income in TX (no income tax), but unsure of schedule GL on pa40. How do I calculate how much PA wants from my income in TX?

My permanent address is in PA, but all my income earned is from TX (no income tax). Last year I owed PA taxes from my income in TX. It says I don't owe PA any money this year. I was confused about the schedule G-L on pa40 because I'm not sure if the amount I should enter is 0 for tax portion owed. And I don't know how to calculate how much tax I owe PA, or what form to use/if I can file that online or if I should ask for an extension

Go back to the W2 screen, and enter TX in box 15.  If you leave that blank (as it probably is on the W2), PA programming is not pulling the income over to the PA return.  But you are correct that PA does tax you on this income, so this is how you make sure the income pulls over and is reported.
