Hi shannonhayward-g,
Welcome to Community! Having the ability to categorize your transactions is a great way to organize your business and personal expenses to ensure they hit the correct line on your Schedule C. In this situation, I recommend reaching out to the QuickBooks Self Employed support team for assistance with creating the category you need to help reach your goal. In addition, here's an article for your reference for categorizing transactions.
I hope this has been helpful. Enjoy the rest of your day!
