I should have been more specific -- the software will prepare a MS corporate return but in past years it could not be e-filed.  Does anybody know if this has, or will be, rectified in the current year?

In my "clicking around" at the link provided I don't see this issue specifically addressed.

At this point, why would there be any state's corporate return that couldn't be e-filed through ProSeries?  I'd like to understand the logic, so that I can move up to another package this year if necessary.
