In order to claim the refund ProSeries is telling me I need to attach the proof of appointment. I have attached the PDF document E-File>Attach PDF Files and labeled the PDF attachment as Form 1310. The error still exists and I am unsure why it will not go away now. 

NOTE: I did notice if I select option C (even though a court appointed rep has been assigned) and answer the questions in Part III I can get the error to go away. Would this be considered a valid submission of the return?
