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.

Any clarification is welcomed.

Thank you!
