Hi anna-lee,

There are two things we can consider that will help you enter a check received from a vendor (supplier).

If you enter bills to track your expenses, you can create a supplier credit.

1. Click the Plus (+) icon.
2. Select Supplier Credit.
3. In the Supplier drop-down menu, select your supplier.
4. Depending on how you record purchases with this supplier, enter the Category details or Item details. Usually, this is the category, product, or service you’re getting a credit for.
5. Click Save and close.

Then, apply supplier credits to a bill. Here how:

1. Click the Plus (+) icon.
2. Select Pay Bills.
3. Select a bill for your supplier from the list. You'll see the available credit with this supplier in the Credit Applied field.
4. Complete the rest of the fields like you normally do.

If you enter expenses or write checks, you'll want to consider entering bills in QuickBooks Online (QBO). This way you can track your account balance and credits using Accounts Payable. Otherwise, you can enter a note to remind yourself about this credit in the future.

Feel free to let me know if you need anything else. I'd be here to help.
