Not sure what you mean by "event" -- the child must be under the age of 17 for the tax year, and must have a Social Security number. The CTC is affected by the income you earn from working. The child had to live with you for at least half of the tax year.
Give us some details about the child you tried to get the CTC for.....
CHILD TAX CREDIT
There was lots of hype in the news about the new $2000 Child Tax Credit when the tax law changed for 2018 and beyond. Unfortunately, some people do not yet understand that it does not mean they will automatically receive $2000 per child just for filing a tax return.
Do not assume your refund will include $2000 per child for child tax credits. It does not work that way. The CTC is used first to reduce your tax liability to zero. After that, there is a refundable portion —up to $1400 — called the Additional Child Tax Credit that is calculated based on the amount of income you earned. You do not necessarily get the maximum amount. You get 15% of the amount of income earned above $2500--UP to the maximum amount possible.
If your child turned 17 in 2020, even on the last day of 2020, you do not get the child tax credit. There are no exceptions to the rule. You can still claim your child as a dependent.
Your child must have a Social Security number to get the CTC.
If your child was born in 2020 you need to say the child lived with you for the WHOLE year.
If your child lived with you for less than half the year you cannot get CTC.
If you did not earn at least $2500 you cannot receive the additional child tax credit. Beyond that amount the CTC you receive is affected by your tax liability and the amount you earned. You might not get the full $2000 of CTC.
The child tax credit is reduced by $50 for every $1000 of AGI over these limits:
Married filing jointly $400,000 (CTC disappears at $440,000)
Single, Head of Household, Married Filing Separately or qualifying widower $200,000 (CTC disappears at $240,000)
