Get your taxes done using TurboTax

You would have to calculate the depreciation figures. Since you used the mileage allowance in previous years, you would multiply your business miles in 2020 by $0.27. The mileage rate for 2019 is $0.26, 2017 & 2018 is $0.25, 2015 & 2016 is $0.24.  You need to calculate the depreciation for each year and add them together to get the accumulated depreciation asked for . The AMT depreciation would be the same.
