2018 Tax return efile

I am currently working on my 2018 tax returns using Turbo tax.   I generally e-file but because I am past the typical deadline I just assumed that I would have to paper file, which I am totally fine with.  I don't owe and I will be getting a refund ultimately.  The weird thing is; is that Turbo Tax is letting me start to e-file for Federal.  It asked a series of questions for identity purposes but it seems like it will go through.  Is this really going to happen or is this a glitch?  Any one know?
