How come state tax is not being calculated properly for Idaho?

I am confused on what should be used to calculating tax brackets. It seems that the turbotax software is using this formula:  for someone making $50,000/yr the tax is $521.63 plus 6.925% of the amount over $11,279 for a total of $3,203.06. I found information on the idaho tax website that supports this. 

However, another document on the idaho tax website also states states that the tax is $522 plus 6.925% of the amount over $23,279  for a total of  $2,372.43 

Which bracket information is correct?

By the way, why are we not able to post links to URLs in these comments?
