The PA return shows all zeros!

The reason I think there is Pennsylvania withholdings is that there is a diagnostic that says:

"This return has a 1099-MISC with Pennsylvania withholding.  The state withholding is reported on Form PA-40, but it must be entered in screen 50 to properly reflect on the Schedule W-2S/MC (ref. #34600)."

Line 15 (on the K1 and on the input screen) is blank!
