I spoke with Lacerte support after posting my question.  The answer is:

The states must be complete to e-file with the 1120.  Once the 1120 has been e-filed, the states are no longer available to prepare or e-file.  I have about 40 state returns to prepare for this 1120 client - and was unaware of this requirement.

I caution anyone else preparing a consolidated 1120 to NOT e-file until all of the state tax returns are complete and ready to e-file.  You only get once chance.
