I set up a "Security Deposit" entry in the invoice, which was paid along with the balance due. Now, I would like to refund ONLY the security deposit, but I'm running in circles here trying to figure it out.

If I try to create a Refund Receipt, QBO warns me to use the Sales entry instead, and if I ignore that warning and try to select QuickBooks Payment for the payment, it wants the credit card details which I don't have.

If I click the transaction, there's no obvious Refund option. I did find More > Refund, but the warning implies it will be a complete refund, not a partial one.

So my questions are: (1) How can I refund a portion of the original payment to the original payment source, and (2) is there a way to make this easier in the future?
