Hi online community 

I have a doubt. When using the Prior Year Earned Income (2019) in 2021 for a divorced mother with a child. 

My doubt is that in 2019 she was married, but in 2021 she was divorced and only had unemployment. What earned income form 2019 she has to use, her part only or the couple earned income. I am guessing that it is only her part but I would like somebody to confirm it. Have a nice day everybody.
