If my girlfriend claimed head of household, and claimed our daughter, can I still add her to my taxes as a non-dependent?

My girlfriend and I live together, she filed head of household, and also claimed our daughter as we agreed upon. I added my daughter in my info on turbotax but also selected "Yes, I have an agreement with Child's other parent." when prompted to select who would claim her. The next few questions were along the same lines, will the other parent claim child per your 'legal agreement' I selected yes, then got "It turns out Child doesn't count as your dependent". This is fine, I wasn't trying to claim her but it also says "But the good news is she could help you get other tax savings." I added in her SSN and was on my way. after a few more questions it gave my new tax total and it was much higher than I was expecting and says next to my childs name "EIC or Dependent Care Credit Only". 

Is this correct? Should I remove her from my tax info completely?
