I didn't receive any of my child tax credit in 2021 and was told I just press 'no' and I will get it all once I filed. But the amount didn't increase. What does this mean

Sounds like you chose not to receive the Advanced Child Ta Credit.  If that is the case then you should receive all of your allowable child tax credit in your refund.  I don't understand what you mean by did the amount did not increase.

For tax year 2021, the Child Tax Credit is increased from $2,000 per qualifying child to:

• $3,600 for each qualifying child who has not reached age 6 by the end of 2021, or
• $3,000 for each qualifying child age 6 through 17 at the end of 2021.

Note: The $500 nonrefundable Credit for Other Dependents amount has not changed. For more information about the Credit for Other Dependents, see the instructions for Schedule 8812 (Form 1040)

 

 If you didn’t receive one or more monthly advance Child Tax Credit payments in 2021 for a qualifying child, you can still receive those payments – and the remaining amount of your credit – by claiming the Child Tax Credit for that child when you file a 2021 tax return during the 2022 tax filing season. This includes families who don't normally need to file a return.

 

 

Check 1040 line 28 and see if you got the full amount.  Turbo Tax automatically gave it to you as soon as you entered your children.  So it was already added in before you got to t hat section.
