I've got you covered, Jesse.
Thank you for your thorough explanation of your concern. I'm pleased to assist you with completing a grantee refund for your QuickBooks Online Non-profit account.
To start, let's create a check to refund your grantee.

- Pick the grantee's name in the field.
- In the Category drop-down, pick Accounts Receivable.

- Go back to the (+) New icon and select Bank deposit.
- Pick the same grantee name in the field.
- In the Add funds to this deposit, choose Accounts Receivable.
- Enter the same amount, then click Save and close.

Once ready, apply the bank deposit to your created check by receiving the payments. Heed the steps below for more guidance:
- Return to (+) New and select Receive payments.
- Choose the same grantee in the box.
- Tick the Check and Bank deposit boxes.
