Emigrated to Mexico

My client moved to Mexico in July 2023. She and her older daughther claiming T2201 are both dual citizens (Canada and Mexico).
She receives her deceased husbands pension. She received 2 slips one for the time in Canada and a NR4 for while she was in Mexico. Where do I post this. She also receives CPP, but only received one slip for the year. Do I have to split this and if so, where?

Thanks in advance for all your help.
