You should be able to claim the child care credit. Did you enter both your W-2 and your spouse's W-2? You both have to have income in order to claim the credit. Go back to the summary of your W-2s and make sure each W-2 is entered for the correct person. When you enter a W-2 on a joint return you have to specify whose W-2 it is. If you mistakenly entered both W-2s for the same person, then it looks like the other person had no income.
You do not have to earn $6,000 in order to claim the credit, but you will only be able to get credit for $3,600 of expenses because the amount of expenses you can use for the credit is limited to the earned income of whichever person had the lower income. Enter the full amount that you paid to the daycare. TurboTax will calculate the limit on the expenses.
