Why is Turbotax giving me the $500 Other Dependent Tax Credit instead of the $2000 Child Tax Credit for my newborn?

My daughter was born in September.  I've triple checked all her information, and my wife and make well below the $400k at which the child tax credit starts phasing out.  Anyone else run into this problem and know a fix or is there some hidden requirement for the Child Tax Credit that I can't find?
