If i lived in MD and worked in PA, do I change my PA Taxable Amount to 0?

I went to school and worked in PA last year but my state of residency in MD.  The Compensation Summary says: "
Here's a list of your compensation (wages, tips, etc. from box 16 of Forms W-2).
Edit each compensation entry you want to adjust for Pennsylvania purposes.
If your compensation was not earned while a Pennsylvania resident or from Pennsylvania sources, you will need to edit the entry.
If you were a resident of Indiana, Maryland, New Jersey, Ohio, Virginia or West Virginia (reciprocal wage states) and worked in Pennsylvania you may need to change the wages to zero to claim a refund."..... Do I make the adjustment to my PA Taxable Amount to 0? or select "Entire amount of this income is not taxable in PA?"
