Prepared with the proper questions here is what I found on the IRS website under FAQs for EFIN:

Can my firm e-file a return for a taxpayer which my firm did not prepare?

Yes, as long as my firm gets the return directly from the taxpayer.

I am much obliged and appreciate everyone's help.

In the future I will try a little more due diligence on my own before I bother the busy but helpful community.
