I noticed a much smaller CEITC ($496) on my clients 2020 return compared to 2019 ($3073) Her Earned income was $9508 for 2019 and $7878 for 2020. I noticed the Federal EITC to be correct based on Earned Income only. But for CEITC, the AGI is being used to determine the credit. In this case my client's AGI includes Unemployment income. I also understand my client lost the "YOUNG" CEITC portion of the credit because her child turned 6 in 2020.
Federal EITC uses earned income or AGI, whichever is more. I would guess CAEITC does the same, they do have different limits and credits than federal so you'll have different outcomes. Yes YCTC is for under 6 years old.
