How do I fix a glitch that keeps saying I don't qualify as Head of Household because I didn't pay for more than 50% of household expenses when I selected that I did?

It keeps saying "We checked, and even though you have a dependent, you don't qualify as Head of Household because you didn't pay for more than 50% of household expenses." That's incorrect, obviously, because she had no income, so I paid 100% of expenses and have selected the correct box to indicate that multiple times, and it keeps saying this.
