Can I claim adult child. No income. Provide 100% of support

She must qualify under the "relative dependent" rules, which are different from the "child dependent" rules. Due to her age, she is not a qualifying child. See https://apps.irs.gov/app/vita/content/globalmedia/table_2_dependency_exemption_relative_4012.pdf for the qualifying relative dependent rules.
