The prompts said something about PA still expecting a hand written signature on a form but not to worry about it yet. I never got any more info about it after e-filing?

While completing my Pennsylvania tax return, the prompt mentioned the state still requiring you to mail in a hand written signature - I can't remember what form it stated as it said not to worry about it yet. After filing however, I never received any more information about it - Should I still mail in my return if it was efiled with my federal return?
