new foster parent in Maine

Hi there, I am based in Maine, and I became a foster parent in June 2021 for a newborn who is still with me full-time. I did not acknowledge anything about foster parenting to my taxes for 2021. How should I reflect being a foster parent in my 2022 taxes: is anything needed around naming dependents, expenses, income from foster parenting, or anything else? And is there anything I should correct for 2021?
