Why do you think it is not?  Do you see your standard deduction on line 9?  Follow the big long math calculation on your Form 1040.  TurboTax does an excellent job of calculating if your data is entered correctly.

It looks like I'm paying taxes based on my gross income which makes me owe$8300 instead of getting a refund of $400 when I rough things out on a 1040 form I down loaded. The standard deduction is what's best for me but the Turbo tax program doesn't seem to be subtracting it.
