Here is what I have discovered. After spending 2 hours (yes 2 hours) on the phone with support, I decided to try e-filing the federal and state taxes separately. Turned out that the federal taxes went through fine, even with the "unsupported" 8453-PE included. So, that form is not the problem. My state is NY and now I cannot get that to go through. My support agent (who was super nice and definitely trying very hard to help) and I eventually agreed to just try again today to see if it would go through. I am guessing it is a software issue and it needs to be fixed and updated but, ugh!!!!
