Just to confirm, you previously recorded deposits and assigned the designated fund to those deposits, correct? If that's the case, set up a Service Product called 'Payment Received - XYZ Mission Trip' and select the same designated fund account under the 'Income account' drop-down that you assigned to the deposits. Then, add 'Payment Received - XYZ Mission Trip' to the 2023 invoices as a negative amount for the payments received. That will reduce the invoice balance due by the amount of the payments received and reduce the duplicate entries to the designated fund by a corresponding amount.
