There are options that you can definitely go back and start from scratch. I'm not sure where you see additional charges, but I can tell you this much. To file federally 1040 simple forms are completely free on here. There are certain tax situations that you receive other forms than W-2's that TurboTax will charge you more for. State filing is normally always $29.99. Now, if you choose when you're finalizing to have them take the money you would owe them directly from your tax return instead of out of pocket like with a debit card, they do charge that additional $34.99 on top of it for the convenience of it.
