to take section 179 on a qualified asset in 2020 it must be placed in service anytime in 2020. it could be placed in service on 1/1 or 12/31. either way you are entitled to the maximum 179 deduction for the asset. the same rule applied for 168(k) special depreciation. the date is irrelevant as long as its place in service during the year. By the way, there is no business income limitation for 168(k) depreciation
you are getting the wrong result for the 179. some info you entered is incorrect or there is something you are not telling us. note we can not see your entries or tax file.
if the van is over 6000lbs you should be entitled to fully expense the cost using 179, 168(k) or a combination
key items that must be entered
date placed in service
business miles and total miles
amount of 179 you are taking if anty
the question for economic stimulus qualified property must be yes as well as the question was the property acquired after 9/27/17
if the van is over 6000 lbs
then subject to auto limits should be no
and if you are taking 179 eligible 179 property should be yes
listed property should be no
hopefully, this answers your question
