How can an Ontario resident file a Quebec return for 2020?

My aunt received a benefit from Quebec in January 2020 after moving to Ontario in December 2019.

I filed her federal return with Ontario as her province of residence.

Revenu Quebec now requires me to file a Quebec TP1 return for her, so she can refund the benefit that she should not have received.

The TurboTax app will not let me open Quebec forms.
