Many people have done just as I have said.

Whether or not there are alternatives in ProConnect, I'm not sure, but the fact you are getting several Critical Diagnostics seems to indicate the only way to do it is to do what I suggested (or paper-file the return, after ensuring the correct information is on the correct lines of the tax return).

In my opinion, too many tax preparers are concerned with entering informational "forms" into software, rather than preparing a tax return with the correct information on the correct lines of the tax forms.
