Wow I can't believe that didn't get accepted. I have Pro Series professional like you. I'm looking at the screen now and here's what I did. In the home base View go to EF Center. Highlight the federal and state return for the client only that you want to efile. Then select e-file at top. Go down to electronic filing convert transmit returns extensions. When you do this a box will pop up saying electronic filing options. Down at the bottom uncheck the box that says enable conversion error checking. Then fill in the little circle that says convert and transmit selected return. Then hit okay and that should work unless the rocket scientists at Intuit change something again since this morning when I e-filed.
