How to remove a deposit that's linked to an invoice.

Hi there, @lcheung72.

You'll want to go to open the paid invoice and unlinked the deposit from there. Here's how.

In your QuickBooks Online (QBO) account:

1. Go to the Sales menu.
2. Select the Invoices tab.
3. Locate and select the invoice.
4. Click the 1 payment made link and select the date link to open the payment transaction. 
5. Uncheck the invoice to unlinked it to the payment and click Save and close. 

I'd also recommend contacting your accountant for guidance. This way, we can ensure the accuracy of your accounts after making these changes.
