Getting a strange rejection error

If 'Form4972Ind' in the return is checked, then form 4972 must be attached to 'Form4972Ind'

I searched previous questions and found one back in early February, with an answer saying to resubmit.

I have done that a couple of times, shut down Proseries and restarted before the 2nd resubmittion. Still getting the message, the earlier post did not have a note that the OP ever figured something out. 

Any ideas I can try  would be appreciated.

BTW There is no retirement anywhere in the return, Couple are both still working. No 4972 has ever been included for this client.
