I’m a single mother with 2 kids currently. 

2020 Last year I made about 17000 and had only one child. I received all three stimulus checks plus my 2020 tax refund I had money in savings all together I had about 25000 saved. I became pregnant sept 2020. I only work Jan and feb (after taxes my checks together were maybe 1200) I then decided to take off to spend time with my daughter before my son was born. I also received child support (not court ordered he just gives it to me willingly) from my baby’s father with that and money I had saved so I wasn’t worried money I knew I had enough. I qualified for the child tax credit. I’m currently only receiving it for my daughter as The portals not available to update and add my son. I do not plan on going back to work until 2022. My question is when I file 2021 taxes will I receive the second half of the ctc for my daughter and the full amount for my son ? Or will I have to pay back the $1800 (she’s 3-$300x6) ) I received since I didn’t make in 2021 no where close to what I had in 2020?
