I used a vehicle in my business and took the std. mileage deduction from 7/2013 through the end of 2016. In all of 2017, I used that vehicle in a different business (quit using it in the other business, which wasn't doing well). That vehicle was involuntarily exchanged for another in 10/2017 for a different vehicle. When I reach the review portion of Turbo Tax, it tells me that the 1st vehicle can't be linked to the new Schedule C and that the "Link1 line should be blank"; when I go into the form and unlink it, then it tells me that "Link 1 line must NOT be blank". How can I treat this Like Kind Exchange (involuntary disposition) properly and get the taxes done?
