How do I claim the Saskatchewan Graduate Retention bonus in the second year after refile

I am helping my daughter - she qualified for the retention bonus in 2020 but didn't claim it at that time. I helped her refile and a few days ago she has received a notice-of-reassessment for tax-year 2020. We would like to refile for 2021 to get caught up before filing her return for 2022.

Turbotax 2021 (download) asks us to: Enter your Saskatchewan graduate tuition tax credit amount from your 2020 notice of assessment or notice of reassessment. 

I cannot find any specific mention of the graduate tuition tax credit amount on the 2020 NO-reassessment she received.

Has this happened to anyone else? Can the information we need be found anywhere else? Should we contact CRA? Any other suggestions?
