They're not. You just use the program the way it's intended and designed to be used, enter all your data and e-file the return to the IRS.
As a first time user of the program, I HIGHLY HIGHLY recommend you use the CD/Desktop version that you physically install on your computer. It's much easier to navigate and much easier to fix problems and mistakes with. As a first time user of the program, you will have lots of mistakes to go back and correct. If you do this with the online version, then depending on the complexity of your return, you WILL NOT be a happy camper.
