I believe Form IT-8453-OL, Declaration of Electronic Filing is causing an issue when attempting to e-file State of Indiana tax return via Turbo Tax. I found a Turbo Tax link that shows all Indiana forms, and this particular one it's showing as unsupported.
The problem is that this form appears to be mandatory for e-filing. So this sounds like a circular reference error at this point.
The software won't let me delete this form.
