How do you process a refund for a client invoice?

Welcome to the Community, shannon103.

Let me share some information on how to process a refund in QuickBooks Self-Employed.

You can access QuickBooks Payments to process a refund for a client. Please note that you can process the refund within six months from the date of the sale.

Here's how:

1. Log in to your QuickBooks Payments account.
2. From the Processing Tools drop-down, select Reverse a Transaction.
3. Fill out the necessary fields and select Search.
4. Choose the transaction(s) you want to refund, then Submit.

Refer to this article for additional details: Void or refund transactions in QuickBooks Payments.

In addition, I've added this article for your future reference that provides an overview of how to categorize transactions: Schedule C and expense categories in QuickBooks Solopreneur and QuickBooks Self-Employed.

If you have additional questions about processing refunds or other issues, post them in the comments. I'll be sure to lend a hand.
