TL11A slip

I have a client who’s TL11A slip for a university attended in the US says $28,380 was paid in for tuition in 2020 but the corresponding 1098 US tuition slip says $48,446 with $20,000 for Scholarships or grants. It appears that the school netted the scholarships even though they are not supposed to. She is in full time attendance toward a bachelor’s degree and the school is listed on CRA’s List of Designated Educational Institutions.

Should I have my client go back and have this amended? How would I report the scholarship income on her return? Is there a maximum amount of tuition credits that can be carried forward?

Thank you!
