Renew 1-year contract

Hi, I want to renew my discount 1-year contract (which will end on Aug 19, 2021) as my roommate and I will continue to live at the current address. I notice that my next autopayment will be on September 7th but it's $117, compared to the previous $91's.

I can't find where to renew my contract in my account, could you please help me with it?
