Hey Colin,
Thanks for reaching out on the Community! I'm here to point you in the right direction.
I recommend reaching out to the QuickBooks Self-Employed team. They'll be able to help guide you in recording your vehicle expense considering your situation. You can reach out to them using the in-app Chat support, or send them an email here: https://help.quickbooks.intuit.com/en_CA/contact.
I'd also encourage you to consult with your accountant on this one. They'll give you great advice for how to record this expense until it comes time for your end-of-year breakdown.
If you have any questions, please let me know.
Have a great day!
