Welcome to the Community space, @MicGrow
Currently, adding credit notes to an invoice isn't available in QuickBooks Self-Employed. As a workaround, you can record the refund you received from Amazon by creating a transaction and assigning it to the correct category.
Here's how:
- From the Transaction tab, select Add Transaction.
- Type in the amount and description.
- Click the Select a category option and choose the correct category of your transaction. Check out this article: Schedule C and expense categories in QuickBooks Solopreneur and QuickBooks Self-Employed.
- Select Save.
For more info, check out this article: Manually add transactions in QuickBooks Self-Employed.
Also, I recommend reaching out to your accountant to guide you on where to record transactions correctly.

I'm glad to have you here. Please come back if you have additional questions about categorizing transactions. I'll be willing to help. Have a good one.
