I just researched and answered my own question. According to the PA-40 instructions on their website:
"For E-Filed Returns:
If you file your PA-40 electronically, you are not required to submit an
actual copy of your W-2, 1099-R, 1099-MISC, or 1099-NEC forms unless
certain conditions exist with respect to those forms. For Forms 1099-
MISC, 1099-NEC, and 1099-R, you are only required to submit actual
copies of these forms if there is PA tax withholding reported on the forms."
Hope this helps someone else.
