HOH really only works in these situations

1) you are not married but have dependents

2) you are married but have been separated for at least 6 months (and each state may have different rules that defines when the 6 months begins - in some states a judicial order begins the 6 month period).

for example, if you were legally married on 12/31/19 and you spouse walked out on you in late July, 2019 you are either married-joint or married-separate.  HOH is not an option. 

OK ... read that screen (and every screen)  slowly ... it asks for your MARITAL Status not your FILING status at this point.  Later in the interview, AFTER you have entered in a qualifying child, you may be offered the HOH filing status.
