Thanks for joining this thread, @sweetsue1010. Let me share some information about credits in QuickBooks.

Let's make sure to select your Accounts Payable account for your deposit so you can successfully record your vendor's credit. This way, it'll be also recorded as an available credit to be applied as payments for your bills. 

Here's how:

1. Select Banking and click Make Deposits.
2. Under RECEIVED FROM, choose your vendor.
3. On the FROM ACCOUNT column, select your Accounts Payable account.
4. Enter the amount of your vendor's credit.
5. Click Save & Close.

Then, link the deposit to your vendor's credit:

1. Proceed to Vendors and choose Enter Bills.
2. Select Credit and choose your vendor.
3. Select the account or item of your vendor's credit.
4. Enter the amount.
5. Lastly, click Save & Close.

Once done, you can now successfully pay your bills with the vendor's credit you just recorded. For more information, you may check out this article: Record a Vendor Refund in QuickBooks Desktop.
