Hello, Chris_Eagland.
QuickBooks Self-Employed (QBSE) is commonly used to track income, expenses, mileage, and tax info. This type of QuickBooks is designed specifically for independent contractors and freelancers at year-end. QuickBooks Online (QBO) on the other hand is preferred by small businesses because of the chart of accounts feature.
If so you would record this percentage amount using an expense transaction, on the expense select the business bank account under 'Payment account' and enter an expense account on the Category drop-down. This way, they can guide you on the correct category to use for making sure your books are accurate.
I'm also sharing this article for additional reference about categories in QBSE: Custom categories in QuickBooks Self-Employed.
