Yep! The Free Fillable Forms thing is roughly equivalent to printing out all the forms and filling them in by hand, but you're just doing it with forms on the internet instead of mailing them in. Most peoples' taxes aren't rocket science, you definitely don't have to pay for tax prep software if you're capable of following instructions and doing middle school level math.
I can do those two things (mostly) but the slightly tricky bit is when the form requirements change e.g. you need to suddenly provide a new form because the guy in charge said so. I'm guessing the software handles that for you.
