"Usually" it is because you do not have enough other Itemized Deductions entered such that the Std Deduction has been exceeded yet. Keep adding all your Potential deductions,a dn the software will switch over when the proper level is reached .
Std Ded for a single person is 12,200
Std Ded for MFJ ........................is 24,400 (LOTS of itemized deductions needed to exceed that)
with some extra thrown in for each spouse who is 65 or older (or blind)
