The child-related credits can be confusing.
You do not get education credits for preschoolers. Education credits are generally entered for college students. You do not enter anything about education credit on a W-4.
The W-4 is asking you about the child tax credit----which you can get for your children who are under the age of 17.

If you pay someone to take care of your child so you can work, or your child attends preK so you can work, you can enter information for the child and dependent care credit--not education credit----when you prepare your tax return.
