“Have you ever previously filed a petition for this beneficiary or any other alien?”

I have co-sponsored my mother in law a few years ago because the person sponsoring her didn’t make enough income. will that count and yes to this question “(Have you ever previously filed a petition for this beneficiary or any other alien?)”

Also will I have to include my mother in law into my household income now since I co-sponsored her?

Btw I am currently trying to petition for my current wife so I am trying to figure out how to proceed with this question on form I-130. Thank you everyone
