I appreciate your effort in adding a detailed scenario with your concern, @tmoney5252. Let's work together to make things right so you find a match for the batch deposit in QuickBooks Online (QBO).

To fix this, you'll need to undo first the transaction from the Categorized tab to void the resolve difference and the transaction goes back to the For Review tab. After that, we can follow the process to settle this issue and you'll be able to find a match for the deposit payment.

Firstly, you'll want to Receive payment directly since you've already created an invoice that amounted to $ 1,650. Then, deposit the Undeposited funds or Payments to the deposit account.

After that, create a Bank Deposit for the invoice payment. On the Add Funds to this deposit section, enters the expense refund for Customer B with an amount of -600. For the accounts to use, I recommend reaching out to your accountant or a QuickBooks Certified ProAdvisor. That way, they can guide you with the appropriate process and ensure the accuracy of your books. Then click Save and close. After this, you can now find a match for the deposit transaction on the For Review tab.
