@hadjwold - please go back to your bank account statements and review what you received from July - Dec, 2021. With two children under 6, did you receive $600 per month for 6 months, which is the normal or expected payment? DO NO RELY ON YOUR MEMORY. Please take the time to open all 6 of those bank statements!
What you told turbo tax is you received $2400 (line 14f of Form 8812).
but the IRS believes that it sent you $3600, hence the difference owed of $1200.
Also, what year(s) were your children born? if they were born in 2016 or afterways, they are 'under 6' for this tax credit. You can see that on Line 4a and 4b of Form 8812. there should be a '2' on those lines for you. Please confirm that when you respond.
let me know what you find!
