Tuition slip, refunded and canada caregiver

I have client that attended university winter/spring/summer 2021. She became quite ill and unable to attend school in the fall. the university refunded her fall tuition in Feb 2022 but slip for 2021 was uploaded on CRA portal. Should i just take out the portion of tuition refunded?
Also, i have transmitted dtc and assume approval forthcoming.
On the info screen on tax cycle i ticked that she was unable to attend school full time - although she did for 3/4 of year. I did this because i am trying to claim canada caregiver for elig dependent over 18+
trying to process to minimize any issues with CRA
thanks for any input
