When you use the standard mileage method, you have to figure out the depreciation equivalent based on those miles. 

Here is a chart showing the amounts:

Say you drove 1000 miles in 2020 and 1000 miles in 2019.

1000 miles X .27 = $270

1000 miles X .26 = $260

270 + 260 = $530 depreciation

Unless you use a different figure, TurboTax will assume you depreciated the vehicle to the full extent allowed.
