I also am not registered to E-file (I am pretty much retired and prepare less than 5 returns a year).  I recently relocated and need for my "Firm" address to be updated on the returns.  I updated my new mailing address with myproconnect.intuit.  Why can I no longer update my Firm address?  My new address shows up on the IRS PTIN site.  I DO NOT WANT TO HAVE AN EFILE NUMBER.  WHY IS THIS A PROBLEM?  (sorry for shouting),
