If I disposed of my car in 2018, what do I put in Basis for gain/loss and Basis for AMT gain/loss?

When you say disposed, did you donate or sell?

Junked.  Thank you.

is this related to a business or personal vehicle?

Traded in a 2014 car used 75% for business purposes.  We never depreciated the 2014 car.  We just used the standard deduction.
