Rental expenses are not itemized deductions. Those are separate rental deductions.
If your itemized deductions (which are different from your rental deductions) are larger than your Standard Deduction, I'm not sure exactly why it is doing that. In some cases it could be due to Alternative Minimum Tax, but there are a couple of other legitimate reasons it would choose the Standard Deduction (but it also could be an error).
Some of those summary screens tend to be very misleading. It might be showing you what you are actually allowed to claim as Itemized deductions - which is $0 because you are claiming the Standard Deduction instead.
