Credit for Other Dependents

In 2018 Turbo Tax Deluxe, in the "Learn More" section, for the question, "Does my dependent qualify for the Credit for Other Dependents?," the first qualification listed is "You are claiming a dependent that lived in your home for the entire year."

Is this true? My understanding is that if you provided more than half of the dependent's support during 2018, you would qualify, even though the dependent may not have lived with the taxpayer for the entire year (which is my case). Turbo Tax 2018 IS including the $500 credit on my tax return, so this seems to support my understanding.

Can someone clarify, please? (I know, I'm down to the wire as my tax return is due today!)

Thanks!
