It could be that you have an alternative tax situation that may limit your standard deduction. If your income is over $113,400, you may be subject for paying Alternative Minimum Tax(AMT) in addition to your regular income taxes. Please read this Turbo Tax link for more details.
Also the standard deduction is not taken into account for AMT purposes thus is added back as AMT income. In addition, certain itemized expenses such as state and local income tax, real estate taxes and personal property taxes are added back as AMT income. Your mortgage interest and medical expenses are still allowed and may have accounted for the difference between itemized and standard deduction.
