there is a box that needs to be checked on the info worksheet
it says check this box if you are married filing separately and your spouse itemized deductions
in step mode
to get to these questions answer yes to were you married?
then it asks about filing a return together with your spouse which is no (MFS)
it'll ask spouse's first name
and then whether either (spouse's name) or you claim itemized deductions which must be checked,
there are other check boxes on that page and the next so read them carefully
if the questions are answered properly you should come to a page that says we have chsen a filinf status for you and in green Married filing separately
continuing you arrive at a page that says itemized deductions and gives the reason - spouse is itemizing
