Why is my truck loan showing as income?

I'll share some information about why the track loan is showing as income so you'll be guided on what to do, mthomas92551

Once you categorize, QuickBooks puts your transactions on the correct line of your Schedule C. This organizes your income and expenses so you'll know what areas of your self-employed business have the most significant impact.

The main reason why your loan transaction is showing as income it's because of how you've categorized truck loans in QuickBooks Self-Employed (QBSE).  You'll have to make sure that you're using the correct category so it will show the way you want it to be in your Profit and Loss report. 

Also, whether your income increases or decreases, depends on how you categorize your transactions. 

Furthermore, QuickBooks is designed to help you record your income and expenses, track mileage, and prepare your Schedule C. To give you an overview of everything with QBSE, check out this article for your reference: QuickBooks Self-Employed Overview.
