Deductions & credits

Thank you for the answer! I paid 17399.98 dollars for the car in 2019, consisting of the cash value of the vehicle (15125), dealer's service fee of 899, license/REG/TIT of 240, and sales tax of 1135.63. 

 

What shall I enter for the total amount paid (cost basis)? Shall I deduct the dealer's fee, license or sales tax from it? 

 

I sold the car to Carvana in 2021 and didn't receive any tax forms.
