I'm trying to efile a form 1065 that has form 3468 and 3800 for a solar panel investment tax credit. The entire ITC has been transfered.  I'm getting reject code F3800-647 that says form 3800 page 4 part II line 4a column B must have a value.  I have a value in there which is the transfer registration number.  The registration number I have is a combination of letters and numbers and is 12 characters long.  What can I do to get this issue fixed so I can efile, or is paper filing the only option? Thanks!

I ended up having to paper file this 1065.  Proseries tech support was useless unfortunately.  The agent was nice and friendly, but didn't have a clue about the tax code, tax law, etc.  They couldn't seem to understand that this was an efile issue and not a program issue.  Tech support appears to work from home too since screaming kids were in the background......
