The link for the form and the instructions can be found on that page.
It is now up to TurboTax to update their software for managing the 8915-e.
I'm reasonably certain that they will do so.
And here's what the IRS said about e-filing.
"Because Form 8915-E is new and impacted by recent legislation, it has not been enabled in XML for e-filing, and e-filed returns are to include an attached PDF of Form 8915-E. As an alternative to attaching a PDF of Form 8915-E, to increase e-filing and reduce paper filing, software providers may instead include with the e-filed return a general dependency statement that includes all the information requested on Form 8915-E if they have issues with attaching a PDF."
The IRS also gives a procedure presumably for the software developers for providing the information via e-file. Again, I have to figure with TT being an industry leader, that they will figure out a way for handling it.
