Anyways, after talking to the TurboTax CPA (great service BTW), and spending over an hour, they promised to research and respond. Here's what I received:
Dear XXXXX,
Thank you for contacting TurboTax Support.
As we discussed during our call, you had a question regarding to your business vehicle deduction. Utilizing our smartlook screenshare, we were able to look at your screen and look at your entry. However, we could not resolve your issue during our call, and I told you that we would call back.
If you placed a heavy vehicle into service in 2017, you can get a 50% first-year bonus depreciation. There is $25,000 limitation applies. Refer the following IRS publication 960, page 20.

After we ended our call, my manager found the following article from Tesla Motor Club. It explains how to calculate Section 179 Deduction based on $100,000 Tesla.
Time running out for Model X 2017 *massive* business-use tax deduction
The manager and I worked on your case after our call. Created the same entry in our end, and tried to bring up the depreciation.
After two hours we worked on the depreciation, we came to the conclusion that our program was not able to bring up the 179 deduction properly. The matter was out of scope for our program and will probably be included in our 2019 version.
We apologize that we are unable to resolve your issue.
