How do I delete Child Tax Credit Form because I have to fill foreign income Form 2555

I have two kid whose age are below 17. and Turbotax show I can fill Child Tax Credit to get 4000$ return. However, I have foreign income and need to fill form 2555.  So I can not apply for Child Tax Credit. But I don't know how to delete the form for Child Tax Credit.  I try to change to Form status and choose the form and delete it. However, when I change to easy mode and review it. The Child Tax Credit 4000$ is still in the form.
