I learned to paper file while working as an IRS volunteer for a few years. It really helps to know the fundamentals of a 1040 and a Schedule A when you're using Turbo Tax or other software. Best thing is to try your taxes on paper, and when you run into questions turn to the instructions book to learn the rules; then compare after Turbo Tax and see what you may have overlooked.
Knowledge is power! Mastering your tax situation will help you make positive decisions throughout the year regarding charitable contributions, tax advantaged investing, filling out your w4 at work, etc.
P.S. Don't listen to people who are saying, "I deduct everything" or "My guy takes care of it for me." They're most likely cheating and don;t even know it.
