I'm here to provide some insights about chargeback in QBO, @Dillet.

QuickBooks serves as a messenger between you and the card issuing bank. Thus, the transaction can be disputed. This is per the credit card associations' rules and regulations. 

Most disputes can be filed up to 270 days after the transaction was processed, and sometimes even longer, depending on the specific bank. Intuit acts as the intermediary in this process, serving as the link between you and the card issuing bank. We don't have control in this process. When accepting credit card payments, there is a possibility that the transaction may be disputed.

Moreover, I've added this article for a more detailed guide to help you handle credit card chargebacks and learn what a chargeback is: Handle chargebacks and retrieval requests for QuickBooks Payments.

Furthermore, you can save this guide for future reference in balancing your QuickBooks and bank or credit statements: Reconcile an account in QBO.

I'll be glad to help you if you have any other questions about refunding charges in QuickBooks.​ Have a good one.
