How do I pay for tuition

I’m a high school senior who is attending UIC fall 2018. I am not sure how to pay the tuitions (the big amount).
We didn’t get any mails related to the bill.
The only thing I paid was the housing application fee which seems weird. That’s it for now?
Should we just wait until they reach out to us?
Yes I do see payment plans but I have no idea where to pay.
