You both might be able to file as Head of Household if you both have dependents and other requirements are met. Can you give some more details about your case? 

The scenario is stated in the link in the original post:

1. You're not married, or you’re considered unmarried on the last day of the year.
2. You paid more than half of the cost of keeping up a home, that was your home and the main home of your child for more than one-half of the year.
3. Your child is your qualifying child for purposes other than the dependency exemption and the child tax credit.  

There is just no way to do it in the current version of Turbotax,  I was able to do it in the 2019 version.

Thank you that worked!
