I then went to the "Deductions & Credits"
You can't and don't claim SCH C business expenses there. Everything is reported in the SCH C section of the program. You need to delete everything you entered concerning vehicle expenses under the deductions and credits section.
If you'll take a look, in the business expenses section there's a sub-section for business vehicle expenses.
Precisely how you get to that depends on what version of the program you're using, and if it's the CD you installed on your computer, or the online version of self-employed.
