You can look at the different packages here.  If you already bought one, you should be able to figure out which one you bought.

Most packages include many or unlimited number of tax returns, but if you bought the a Pay-Per-Return one, then you need to pay for each tax return separately.  There is no separate, additional fee for e-filing (it comes with the cost that you paid).

You can prepare the tax return itself for 'free', but when you want to print or e-file, that is when the program 'charges' you  (either as subtracting one of the returns you bought, or charging you one Pay-Per-Return fee).
