FAFSA asking for forms?

when I log into my UCLA fafsa, as well as other schools I got into such as UCSB, it doesn’t give me an unofficial award since it says that I still need to submit forms. I have already submitted the fafsa through the website and it says it has been delivered. Does anyone know when the deadline for turning in the requested forms is? Or why I was asked for the forms and other people weren’t? Please help! Thank you!!!
