I've donated to the organization Children International and received a receipt to be used for tax deduction. Is that eligible as supporting or claiming a dependent?

I've donated to Children's International in the late fall of 2018 and I received what they call a "tax receipt" to be used for income-tax purposes. Would this count as claiming a child as a dependent or supporting the child? If not, where exactly do I provide the information that the donation was done through a charity organization?
