I completed Form 8824 for my 2017 taxes; I traded in a personal/business car for a new one at a dealership; I think I was wrong to complete? Can I correct it if I amend?
I traded in a car to a dealership in 2017 and purchased a new one. I use the car for personal and business reasons (I drive a lot for work). I completed Form 8824 by accident, not realizing what it really was. Now, I'm being prompted to complete it again when I file my 2018 taxes. Not sure what to put, leave it blank, amend my 2017 taxes?
