So if you mark the Info Worksheet to e-file the State return, Indiana is not a choice.  You can go to the Indiana return & mark the box on the IT40 to amend, but you cannot make the return ready to e-file.  So I printed the forms for my client to mail in as this seems to be my only option after another 1hr & 30 min on the phone with tech support today. It seems ProSeries must not have approval for Individual e-filing for amended returns.
