What do you mean? So have you fought the villains or not? There's nothing that you HAVE TO do before that fight aside from following Uraraka's story.
If you already fought them, go to sleep and check on her on the following day.
Oh right, then how many villain did you fight?
Anyway, just follow the last few steps of this tutorial.
