I was charged weekly for usage of company van for HVAC work. It was for work only. How and where do I add this expense?

Also: I paid for gas to and from all jobs.

if you are a W-2 employee, these expenses are no longer deductible,.

This is common practice and somewhat IRS mandated.  Essentially you are just paying for your own commuting cost (you take the van home at night and have it to drive to work the next morning). The cost of commuting is not deductible. The IRS does not allow that to be a tax free employee benefit, so your employer either charges you or imputes income for the benefit.
