FASFA question

I am 18 years old, and I have a child. I live with my father currently. I was filling out the application and it said I’m classified as an independent. And then when I proceeded, it took me to put 2017 tax returns, but at that time I was 16-17 years old. And I know for a fact that I was under my fathers taxes, as a dependent. So since I didn’t file in 2017.... do I have to go back and put my fathers information??? Or out of the 3 things I have to select (which are A. Already completed B. Will file C. Not going to File....) Do I put C? Or???? I don’t know I’m confused! I just want to get started so my daughter and I can have a good future.
