$6050 seems correct based in what info you supplied. However, did you get any advance CTC payments and were these entered on the 8812 - could be like 1/2 the max for 2021 or $3300 if so line 28 of your 1040 would only be $2750 (the advance was based on your 2020 AGI)
what number did the IRS come up with?
