5695 - - should I fill out in case?

Hi, I am a homeowner who got a new metal roof in 2019. TT states the form will not be available until 1-29-19.

 

If the credit has expired, should I still wait till form is available to fill out and file my taxes after that time on the chance that something might change with Congress, or is a moot point?

 

I'm trying to decide if waiting till after the 29th is beneficial or if the fact that the credit expired in 2017 means I should go ahead and file now.
