We had paper filed a 990-T and received word that it must be electronically filed. I literally just set the 990-T to efile in Screen 1 and attempted to transmit. The return failed transmission and the  resolution given was "We are working diligently on final approval with the agency so that this return type can be electronically filed as soon as possible. Blah, blah blah."

It would seem the diagnostic cannot be disregarded. What is Plan B please?
