How do I categorize cash back rewards from my business credit card?

Welcome aboard to the Community, @probationinfo.

I can provide clarifications about how you can categorize the rewards in QuickBooks Self-Employed.

The cashback rewards you get from your credit card account is usually not part of the business income. You can categorize the downloaded transaction as Personal within the system.

You can also seek expert advice from an accounting tax professional for additional information. They'll be able to share further details as to when you can consider some rewards as part of the business income.
 

For additional reference about categories, please visit the categories in QuickBooks Self-Employed article.
