Depreciation forms for S Corp owners

An S Corp who owns a vehicle does not deduct mileage, it deducts actual expenses. So why does Turbo Tax ask for mileage on Form 4562? Is it incorrect to fill that section out (lines 30-36) if you are deducting actual expenses? 

 

Also once the vehicle (only asset) is fully depreciated, would you stop filling out form 4562 or any other of these depreciation forms or worksheets (there are so many!) in subsequent years? Does TurboTax still put it all in there and I just have to go in and delete the unnecessary ones myself, or will it not even ask me to fill them out once the vehicle is fully depreciated? This is for the downloaded version of TT Business. Thanks!
