Incorrect Expense Amount

We had an expense reimbursement submitted with an incorrect amount. The amount submitted was higher than the receipt amount. This made it through 2 approvers and is now at the "Bishop Review" stage. The actual funds have cleared and been deposited in the members account.

What are my options to fix this?

Ask the member to "donate" (a misnomer in this case) the amount overpaid in a donation envelope. The donation slip should be marked to tell the auditor that this is an overpayment. When it is processed, the clerk sets the donation category to budget. This is the standard procedure for returning unspent advances to the budget, as described in the Help Center.
