I check the referenced document which took me to this:
https://care-cdn.prodsupportsite.a.intuit.com/forms-availability/turbotax_fed_mac_individual.html
According to that table the Energy Efficient vehicle form is already available for both printed version and efile.
Yet when I get to that section in Turbo tax it tells me "The energy-efficient vehicles section isn't ready yet."
So, I think there is a bug.
