How do I change vehicle ownership I am being prompted to do that when I already put that I do not own the vehicle?

To qualify to take a self-employed vehicle expense deduction, you must actually own the vehicle you use for work. Otherwise, if you are using someone else's vehicle then you don't qualify for the deduction. 

So, the software is prompting you to change your ownership or you'll need to delete the vehicle expense. Let me know if you have any questions.
