Deductions & credits

I think I better understand how the Credit works, thank you

 

Can you elaborate further on this section of your reply:

 

"You can count work-related payments you make to relatives who aren't your dependents, even if they live in your home. However, don't count any amounts you pay to:

  1. A person for whom you (or your spouse if filing jointly) can claim as a dependent;

  2. Your child (including stepchild or foster child) who was under age 19 at the end of the year, even if he or she isn't your dependent;

  3. A person who was your spouse any time during the year; or

  4. The parent of your qualifying person if your qualifying person is your child and under age 13."

What exactly is the definition of this 'work-related' payments? Is this still part of the Child and Dependent Care Credit or another type of deduction?
