Not sure where you are seeing this...BUT..
1) If you have no income, then they won't file because you have no $$ entered.
2) If you have income, but you can't use free filing because some of yoru entries require a higher version of TTX, then that's true....certain forms can only be prepared in the higher (pay for the software) versions.

IF your income is low enough, there are some IRS Free-file resources that will use most of the extra forms:
