Hi @Diane1308,

I completely understand where you're coming from and I know how it feels when you're experiencing errors when working in a certain task. I'm here to share a few insights you can consider in creating your credit memo.

First off, you can simply create receive payment transaction without selecting your outstanding invoices. This way. it'll create a credit memo for your customer.

That being said, here's how you can create a credit memo from the receive payment window:

1. Go to Customers.
2. Select Receive Payments.
3. Under RECEIVED FROM, choose your customer.
4. From the PAYMENT AMOUNT field, enter the amount.
5. Click Save & Close.
6. Select OK.

In addition, you can check the screenshot I've added below for your visual reference.

As always, You can visit our Help Articles page for QuickBooks Desktop if in case you need to learn some "How do I" steps.

I'll be always my pleasure to help if you have any other questions. I'll be keeping an eye for your response.
