First, you will need to use the S-corp software. Be sure you have the right product.
Second, vehicle expense questions are automated for the more common situation where someone is using a passenger automobile for business. In your situation, that may not fit. You still need to report your expenses, but using the passenger auto dialogue may not fit.
I would also add that the first year you fill out a new tax return is a good year to get personalized help, one way or another. You'll be doing a lot of things you haven't done before and I find that small business owners often need coaching not just in filling out the return, but what records to keep, what expenses are deductible, and so much more. It's not uncommon for me to find small business owners making mistakes for years that they've never gotten good advice on how to fix.
