You're asked for recapture info only if you did anything other than "removed for personal use". You need to work back through the vehicle section again from the start. Indicate you stopped using it in 2016, and then on the "Special Handling Required?" screen, click YES. If you click NO, then you have to put in sales information and recapture the deprecation.
The depreciation differs year to year, just like the mileage deduction does. That mileage deduction includes depreciation, so that's why it changes year to year. Even if you did sell the vehicle, I seriously doubt you sold it at a gain....even after you recapture the depreciation. So instead of doing all that math, it's easiest to just declare it removed for personal use.
As a side note, in my personal opinion, the loss you could claim on the sale of a business vehicle, is just not worth all the manual math you have to go through.
