@vladius - can you clarify "single, a head of household".
if you are not married, you need a qualifying relative to file HOH.
Simply living by your self does not meet the IRS definition of "a head of household"
why do you want to force TT to flip from standard to itemized? if you have enough things to itemize, TT will make that determination for you. you get the better of itemized or standard.
