Hi Newtubers - newbie here trying to figure our Adsense/Youtube

My daughter is a Youtube creator, but is under 18 so we are using my Google Adsense account. But adsense is asking me for a website address, but won't let me put in Youtube.

She has my Adsense number connected to her account and she has over the $100 earned that is required to get a payout. But nothing is moving.

Is there something that we're missing?
