Child support papers

I get TANF well because of that, I have to fill out these papers for child support. I got them in the mail, I have to name the father, where he works etc they want to know everything but I don’t know who the dad is or who his name either so what do I do? I don’t even have a name to put down either because he’s the only person I slept with. I was drunk when we hooked up and I didn’t get a chance to get his name, sadly. Can someone help me on what to do? 😔
