How to pay course material fees?

So I’m taking an art class this quarter, and this is the first time I have to pay course material fees for a class. I cannot find out where to pay for it, and I looked under mybill, and course fees did not seem to be included in the bill. Do I submit it to the art office? Or undergraduate office?

Please help!

I’m guessing this is for an art class? I’m not sure how they handle it specifically. For chemistry materials fees, the fees were charged to our accounts after the drop deadline. I’m guessing it’s similar for other classes with materials fees.
