Business Use of a Personal Vehicle ... Sold

OK ... Totally confused on how to deal with the business use of a personal vehicle. This is a truck that I've paid for out of pocket (non business). I never used business income to make payments nor have I ever deducted the cost of the vehicle on our schedule C .. only business miles driven.

 

Every year since 2016 we have deducted business miles. Now for this year 2023 when I indicate that ive sold the truck it now wants me to go through a bunch of calculations and potentially show business income based on the sale value of the vehicle. This is my truck which I paid more then what I sold it for. Why would Turbo Tax be calculating business income? 

 

Thanks!!!
