Deductions & credits

I understand the parameters for taking the deduction. I just simply can't figure out how to add to my return via the Interview questions in TT online. The Interview screens never take me to a place where I can add the 179 deduction in the SK-1 Income section. Under the vehicle section, I have added the vehicle with the normal depreciation information (expenses versus mileage rate, etc.), but once I enter all that information, it never takes me to a screen to take the 179 deduction.
