Do I enter my common-law partner's net income even if she was a non-resident in 2020 and is not filing a tax return?

Under Additional information about <Name> it asks if my common-law partner's net income for 2020 is zero. It then goes on to ask for their "Net income from <Name>'s 2020 federal tax return (Line 23600)".
My common-law partner spent the majority of 2020 in Europe and joined me in Canada in December 2020. She did not earn money in Canada.
