@IRonMaN @Jim-from-Ohio I agree with both of you. I don't expect any of my clients to use this. First of all, I think many people are not even aware of it. Second of all, I'm not sure if it can handle more complicated returns. But remember this is how it was when efile started., i.e. they could only offer certain forms and schedules to be e-filed, and the more complicated forms and schedules could not be efiled. But they gradually built up the system, year after year, and then they eventually mandated it.
