I acknowledge the additional information you have provided, MGB4.

To record the check received from your vendor, you can create a bank deposit. Since the deposit cannot be directly linked to the vendor's credit, you can delete the vendor's credit after creating the deposit. This will ensure the refund is properly recorded and the vendor's credit is cleared.

To create the deposit, you can follow the step-by-step instructions shared by my colleague, @BabyB.

Alternatively, you can consider creating a Journal Entry (JE) to record the check and clear the vendor's credit. Please consult with your accountant to ensure the entry is accurate and aligns with best accounting practices for your business.

For further guidance, please refer to Scenario 3 that outlines The vendor sends a refund check that is not related to an existing bill: Record a vendor refund in QuickBooks Desktop.

Feel free to reach out if you need additional assistance or further clarification.
