I appreciate you for taking all the steps to move the paid invoice, @ejlaccounting. Let me help you create a clearing account in QuickBooks Online.

Here's how:

1. Sign in to your QuickBooks Online account.
2. Click on the Gear icon.
3. Navigate to Chart of Accounts.
4. On the Chart of Accounts window, hit the New tab.
5. Choose a Bank for the Account Type. You may choose any detail type you want for your clearing account.
6. Type in the Name for the clearing account.
7. Make sure you do not type in any amount on the balance before clicking Save and Close.

Then if you prefer to transfer the amount after making a clearing account. You can just create a Journal Entry and before doing so, I highly suggest consulting your accountant for further assistance.
