For the most part, they haven't even updated the 2017 software to show 2017 numbers (it mostly is using 2016 numbers). There is no way they are going to hire a bunch of temporary tax-gurus and programmers to create a new program to analyze a law that MIGHT happen.
If you are concerned about how it is going to affect you, I recommend going to a tax professional that is up-to-date with the current bill.
