That statement implies that if we turn off connected services, we no longer need to log into Intuit.  Is this true?  

It's a valid assumption, but no, it's not true.  We don't use any connected services.  None.  Nada. Zilch.  We did use Payroll services YEARS ago on about 30 files which has long been turned off.  I support approximately 150 active files, most of which have never been connected to any Intuit service and they still stalk us with the Intuit login.  I found a workaround so search my previous posts for instructions.  Bottom line?  Intuit doesn't care, they seem to enjoy playing dumb by tossing out ridiculous suggestions and instructions that have nothing to do with our complaints.
