I think I figured it out. This will be my first year filing taxes with a dependent so I was new to the tax benefits and was getting the terminology confused. I'll write it here to help anyone else.
Three distinct pieces:1. Child Tax Credit (CTC) - This is what Trump changed to $2000, and has nothing to do with child care.
2. Child Care Credit - "The Child and Dependent Care Tax Credit (CDCTC)" . For me, for 1 dependent, and the lower earning spouse AGI > 43K, the max credit I could claim is $600
min( 3000, dependent care expenses)*20% = 600
http://thismatter.com/money/tax/tax-credits/credit-for-child-and-dependent-care-expenses.htm3.Dependent Care FSA -Tax Deduction. For me, can deposit max of 5000, and will reduce Federal Tax, FICA, and State Tax. This comes out to about ~2000.
Summary - I was interchanging the Child Care Credit, and Child Tax Credit and getting confused. I can claim the Child Tax credit. In addition I can also claim either the Child Care Credit or Dependent Care FSA. In my case it will be the dependent care FSA.
