I also have this question. I am using TurboTax Premier Desktop, not ProSeries and need to file an amended return for both Federal and Indiana. When I try to complete my amended return, I get the following Error response:
"Form IT-40: _ The Indiana tax return can't be amended at this time. Do not file the amended return until calculations are finalized in the upcoming release of ProSeries/Indiana."
As others have stated, it does not show this form at all on the list of available forms that one of the experts (RobertB4444) kindly attached to his response.
