Standard Deduction and Depreciation of Rental Property

I would like some clarification.

 

When I filed my taxes, Turbotax said I should take the Standard Deduction.  I was wondering when I take the depreciation on a rental property and also when I take Student loan interest deduction (1098-E) why they are not considered itemized deductions? And why they reduced my taxbale income when I take the Standard deduction?
