I am trying to see when my subscription ends because I want to cancel my subscription. I cannot see anything about it. When I try to cancel it all I get is a message that I have to pay money to cancel it.

you have to pay what you owe, then you can cancel, https://helpx.adobe.com/manage-account/kb/fix-failed-missed-payment.html

you must cancel your subscription within the refund period.  make sure you're aware of the cancellation terms by selecting your plan type (at the top of the page here), https://helpx.adobe.com/manage-account/using/creative-cloud-subscription-terms.html 

for info on how to cancel your subscription, this page describes the few steps involved, https://helpx.adobe.com/manage-account/using/cancel-subscription.html

if you want to cancel but are unable to follow the steps described in the "how to cancel page", you probably have a payment error that you need to repair before cancellation is allowed, https://helpx.adobe.com/manage-account/kb/fix-failed-missed-payment.html
