Hey there, @loridiv. 

Thanks for following the thread. I'm happy to help you remove an accountant. 

If you don't want your accountant to have access to your books anymore, don't sweat, removing them is easy as 1,2,3. I've included the steps to remove an accountant below. 

1. Sign in to QuickBooks Online as a master admin.
2. Go to the Gear Icon and choose Manage Users.
   • 
3. Click on the Accounting firms tab.
   • 
4. Locate the accountant you want to remove.
5. Select the small arrow dropdown in the Action column and then Delete.
   • 
6. Hit Delete to confirm.

You can see more details in Invite or remove accountants from QuickBooks Online. 

That's all there is to it! Let me know if there is anything else that I can do for you. Feel free to reach out to the Community any time you need a helping hand. Take care and enjoy the rest of your day!
