Bank cashed a state dated check

I can share steps on how to record check in QuickBooks Desktop, @mtx2.

We can create a credit memo or refund check to give money back or credit to your customers. To proceed, here's how to make one:

1. Go to the Customers menu.
2. Choose Create Credit Memos/Refunds.
3. From the Customer:Job drop-down, select your customer.
4. Enter the items you're giving a credit for, then click Save & Close.

Then, issue the refund in check. 

1. The check is filled out automatically. Click OK.
2. Link the check to the overpayment. 
3. Go to the Customers menu and then choose Receive Payments.
4. From the Received from drop-down, click the Customer.
5. Then, select the Discounts and Credits icon.
6. In the Available Credits section, choose the check you created and then Done.
7. You may see a prompt to Confirm transfer. If you do, select Yes. The amount will be applied automatically to the invoice.
8. Click Save & Close.

If the check was already reconciled, you can simply create a journal entry. Before doing so, contact an accountant to guide you with the appropriate accounts to use.
