Get your taxes done using TurboTax

Okay, what I was doing was dividing line 15 by line 11 which seems like a more true or assessment of your effective tax rate to me.  In any case when I divide line 24 by line 11 I get 18.38%  not the 5.99% as stated by the summary.  I'd like to know how TurboTax got the 5.99%.  Any idea?
