An earlier question/response on here has me confused. It sounded like you can only receive the child tax credit if you reported expenses paid to take care of the child on form 2441. I received the credit in 2020 but I didn't report any expenses in 2020 on this form other than unused dependent care benefits (which was from a DCFSA). Do you need to report expenses to receive it?
And, are the requirements different in 2021 than in 2020?
