7th state return not showing as filed

My nephew had W-2 income in multiple states.  Everything is fine except for the Pennsylvania return, which was the 7th state return.  I e-filed it through TT on February 14th, it went clear through to the transmitted successfully page and did I want to print a copy.  When I check the e-filing status all the returns show as accepted except Pennsylvania doesn't show up at all.  When I  saw this on the 19th, I thought I must have done something wrong, so I went through the steps again and it let me e-file again, yet it still isn't showing up at all.  My nephew has checked his email - nothing for this state return.  Any ideas?
