Been using E-Fiile for Fed. & State income taxes for years and have never had a bobble with 'em. Quick, easy ,clean.
Try TaxAct.com. It is free (I really, really like FREE) to fill in the form and to file it.
You can start entering your info and if you are interrupted or have to leave the computer you can save and log out and when you log back on you can go to where you left off. Pretty neat!
