I got vendor refund CHECK for credits issued. How do I record deposit of his check to offset credits I already entered? I DON'T USE BILL PAY.

It's nice to have you here today, bluemarble41075.

When you enter a vendor credit, it leaves an open balance to your account. This means that you need to link the credit to a transaction or future bills to offset the balance.

Otherwise, you'll need to delete the Vendor Credit and just simply create a Bank deposit to record deposit of your vendor's check.

First, let's locate the Vendor credit through the Advance Search feature.

1. Click the  Magnifying Glass icon.
2. Enter the date, amount, or transaction number you’re looking for, then select the desired transaction.
3. If the transaction you're looking for does not appear on the results list, select Advanced Search.
4. Adjust the filters to find the type of data you want.
   
5. Locate the Vendor Credit.
6. Scroll down and click More. Choose Delete. 

Here's how to record a Bank deposit:

1. Go to the +New icon.
2. Under Other, choose Bank deposit.
3. Fill in the necessary information.
4. Click Save and close.

No do not delete the vendor credit, @Charies_M  is wrong

deposit the refund check and use accounts payable, vendor name as the source for the deposit

then open bill pay and pay the "bill" the deposit created with the credits, save
