The company purchased a utility vehicle (Golf car). it's used during the course of surveys in the outdoor amusement consulting business. How do I deduct it?

You don't deduct is directly. It's a company asset that has to be capitalized and depreciated over time. Being a golf cart that is not street legal, I don't think it would qualify as a vehicle business asset, but instead would be entered in the Business Assets section of the program.

Golf carts can become street legal in some jurisdictions

I don't think it really matters. But I'm not sure if it would be claimed in the Business Vehicle Expense expense section or not. I don't think so, because working it as such through the program it's asking for things like mileage records, if it's used exclusively for business, do you have another vehicle for personal use, etc. Going on what they say the cart is used for, I think it would fall under a general business asset, and not a business vehicle asset.
