So, just to clarify. I would create a credit memo for the customer who is on the deposit that is affected by the refund. Then I would create a journal entry transfering the credit / refund to the original customer that needed the credit/refund? Example:
Customer A - is due a refund of $50.
Airbnb says that they are going to apply that to the next payout.
Customer B - is the next payout.
Customer B - payout should be $100 dollars, but it is now $50 because of the refund to Customer A.
Credit memo to Customer B. Journal Entry transfering refund from Customer B to Customer A?
