First of all, Intuit, what the heck? This issue should have been caught during all the reviews, not right before we file and after we've paid the efile fee. Bad user experience UX engineering. Additionally, fix the phantom "Untitled" occupation associated with Form 2106. And PA - clean up your act to be more like other states tax returns.
That said, what worked for me using TT Home & Business desktop, is I scrolled to the top of the PA form UE and there is a check box that says something like, "Do not file Form UE." I put a check in that box. I clicked through the rest of the items TT wanted me to fill out on this form with no answers (well I had previously started to answer with my home zip and state as the employer if that matters when you do it) and it let me file the taxes. We'll see if PA throws a fit over it or not.
I went back to the federal return, searched for 2106, jumped to 2106, and also found what @HavingTheTimeOfMyLifeWithTaxes reported, an occupation titled "Untitled". I deleted that even though I had just already filed the federal.
Hope that works for you.
