After days and hours on the phone with untrained tier 1 & 2 support, I figured this 30 SECOND PROCESS out and Trained QB/Intuit Support how to do it.

We had a similar situation, the person who set up QB Desktop no longer was with the company and their Intuit account was connected to the QBD Amin user. 

To "Disassociate" an Intuit user account with the Admin QBD user:

1. Open Company file

2. Select Help menu > "Reset Intuit ID Settings..."

3. Type "Yes" in text field

4. You're presented with 2 options, one if you are accessing the QBD Admin account but not the main Intuit user and one if you are the QBD Admin and the main Intuit user.

5. Log in using the left option and this Intuit account is now "Associated" with QBD Admin user.
