Can this be separated? Here's my dilemma- My @gmail right now is used for the Self Employed and Company A login, but I only want to use it for Self Employed.

Here's how the login looks right now-

[email address removed] is for QB Self Employed & QuickBooks Online- Company A, I can switch between the two.

stellerbooksedh is for QuickBooks Online- Company B (should also be Company A)  

I can help you with setting up the login information for QuickBooks Online for Company A and Company B, @stellerbooksedh-.

To achieve this, you can log in to your company A and then create a new profile having same credentials with your company B. Once done, set this user as the Primary admin of the account. 

Here's how:

1. Go to the Gear icon (⚙) and select Manage users.
2. Click on Add user, then enter the user’s name and email address.
3. Provide all the necessary information.
4. Select Send invitation.

To transfer the role:

1. Go back to the Gear icon (⚙) and select Manage users.
2. Find the user you want to make the primary admin.
3. In the User Type column, make sure they are listed as Admin. 
4. Select the ellipsis icon in the Action section. Then, select Change primary admin.
5. Click Change primary admin again to confirm the change.
