Finally received a response to the same Q in this post.  Please read the Q I posted then read their response.  Here was the response (complete crap):

Thank you for contacting Lacerte Email Support. The ITIN (Individual Taxpayer Identification Number) is given to a taxpayer who can't get a Social Security Number. This number is entered Per Client File, and can be changed in the Social Security # entry on screen 1. If you are referring to the EFIN (Electronic Filing Identification Number), which is assigned to the Preparer or Firm, this is assigned via the PREP file. If you need to update the EFIN, you will need to do so from within the program. In this article, we have instructions on how to update your PREP file from within the program. If you have any issues with this, or does not resolve the issue, please call into our support line (number below) to speak with directly an expert so we can properly troubleshoot and resolve the issue.
 
We appreciate your business. If you need further assistance please submit a new e-case or call 800-933-9999 to speak directly with a support agent.
 
Sincerely,
 
Lacerte Support
