Need to change filing status to Head of Household (with a NRA wife)

I live abroad with dependents. I am married to a foreign citizen (non resident alien). 
How can I get TurboTax to provide me with the Head of Household filing option?

I qualify for this status according to the following IRS guidance:

Many thanks,
