Depreciation

Prior to me using TT, my accountant depreciated a business truck using a section 179 deduction and the next two years two different amounts of depreciation and then the same amount for the following  10 years.  I  purchased a new truck at the end of 2024 took a smaller section 179 than I could have and would like to stretch the depreciation out like the prior truck. Of course it's a 5yr class. How do I accomplish what my ex-accountant did?
