Let me share some information and help you clear your undeposited funds account
QuickBooks Online uses the Undeposited Funds account as a temporary holding account for payments received from customers before depositing them in the bank. Also, there's no option to reconcile the undeposited funds account because its not a real bank account.
That being said, you can remove the duplicate sales receipt from your records by deleting it. Let me show you how:
- Go to Accounting, then Chart of accounts.
- Type Undeposited Funds in the search box.
- In the Action column, click on View register.
- Select the duplicate sales receipt, then hit Delete.
- Click Yes to confirm.
