Recording a traded in asset for a new asset paying $3,200 difference

on 12/29/19, I traded a commercial mower I purchased for $12,000 in 2018 used in my business for a 2020 commercial mower and I paid $3,200 difference.  The following is how I entered this in turbo tax.  Added an asset, equipment, cost of $3,200.  I then edited my 2018 asset, indicated that I sold the asset for a sales value of $0.  Is this correct (entering a sale of the asset traded in at $0 then adding an asset at the trade in price of $3,200)?
