We can create another check for that duplicate payment to your vendor. We just need to ensure that we can use it on your future bills for the said vendor. Here's how to do it:

1. Click the + New button in the upper-left corner and select Check.
2. Enter the vendor name in the Payee field and select the affected Bank Account.
3. Enter the Payment date on when the duplicate payment happened.
4. Go to the Category details section and select Accounts Payable in the CATEGORY column.
5. Enter the Amount and the details. You can add a description if necessary.
6. Click Save and close.

This will serve as credit on your vendor's profile. Also, you can apply it as payment on your future bills of the vendor. You can also use this link for reference: How to enter outstanding balances for customers and vendors.

From there, you can start reconciling the account.

We'll be right here if you need additional assistance with this. Have a great day!
