You can't claim it until the IRS fully updates their forms, and approves the software implementation of them.
On one page, TTX indicated they expected to update some of their energy credit forms by 1/29/2020....Don't know if that will include the Charging stations at the same time or not...could be a week late...check back ~1 Feb to see if it's been added in for you...if not, wait another week or two.
Congress passed the largest piece of tax reform legislation in more than three decades. The bill went into place on January 1, 2018, which means that it will affect the taxes of most taxpayers for the 2019 tax year.
Once the new forms receives final approval for electronic filing by IRS, you should be able to successfully file your 2019 return.
