I'm having the same problem. My husband died and this is my first time doing the taxes. PA instructions said to change the order of the primary filer to surviving spouse, but Turbo Tax won't let me. It wants me to file separately. That would be too much work. Also Turbo Tax did not 'remember' that in PA retirement income is not taxable. I haven't tried to fix that yet, since I can't get past the filing status.
