Except most vehicles are subject to the Luxury Limitations, so most vehicles are depreciated over more than 5 years.

@dyzastrofi Do you still need help? If so, did you ever use the Standard Mileage Rate for the vehicle? Was it used 100% for business, or was it also used for personal purposes? What type of truck is it, and is the Gross Vehicle Weight over 6000 pounds? Did you actually use the Straight-line depreciation? If you look at your "all worksheets", it should have a "Depreciation and Amortization Report" that will show some details about depreciation.
