Canadian Student Abroad

My daughter is currently studying in the USA and has been there for 3 years.  We are unsure to file taxes for 2019 now that she has an income from a part-time job in 2019.  The University will only allow her to work so many hours so her income is low.  We did file the past 2 years so that her tuition can be used as credit.  When we file taxes, do we submit her income or is that not needed?

TIA so much.
