Let me provide some information when removing users in QuickBooks to guide you with the process, Kristin.

Only the Master Administrator or Primary Administrator Contact can be able to remove users. You'll want to inform the Master Admin to remove a user from your company. To do so, follow the steps below: 

1. Sign in to My Account. If you need help signing in, check out My Account: Login help.
2. On the Manage your QuickBooks page, select the product or service you’d like to manage.
3. Check if you have the correct account.
4. Scroll down to the Authorized Users section.
5. Select the name of the user you need to delete or remove.
6. Select Remove User.
   • If the user hasn’t taken the action needed in the invitation email, you will see Cancel Invite.
7. Select Remove.

However, if you're the owner of the account, you can let the Primary Admin transfer the role from QuickBooks Desktop to you. You can also go through this article for more details. Transfer the Primary Admin Role In QuickBooks Desktop.
