It’s nice to see you again in the Community, @mikey007.

Deleting the duplicate entries and depositing the rest can help fix the issue. Make sure to link them to your customers’ invoices to avoid having unapplied balances.

Let’s first create a backup for the company file to avoid any accidental data loss. Then, run the Deposit Detail report to delete the duplicate entries.

Here’s how:

1. From the Reports menu, choose Report Center.
2. Pick Banking under the Contributed tab.
3. Look for the Deposit Detail Report, then click Run.
4. Find every duplicate deposits and open them one at a time.
5. In the Make Deposits screen, right-click anywhere and choose Delete Deposit.
6. Hit OK to save the changes.

Once done, deposit the remaining payments. Follow these steps:

1. Click Make Deposits on the Homepage.
2. Pick all the payments you want to deposit in the Payments to Deposit screen, then select OK.
3. Choose your Deposit to account in the Make Deposits window.
4. Review the deposit total and payments to make sure they match. 
5. Select a date for the deposit.
6. Hit Save & Close.
