Business & farm

Double check your numbers to be sure there is not a typo  in the numbers.   When you get to the question of How much do you want to deduct for the business use of this vehicle does it say your business use percentage is 100% or does it say something else?

If it does not say 100% and you cannot find where the error is coming from you can delete the vehicle and re-enter it, paying extra attention to the mileage entries to be sure they are in the correct boxes.  That the total miles are in the top box and miles driven for business are in the next box with commuting miles left blank.
