Im confused whether I should amend my return because I'm being questioned by my state taxes. Saying my wages don't match. I claimed 3300 in taxable dependent care.

I claimed my disabled brother on my taxes. He has no income, he lives with me full-time. He's 45. I didn't have the providers ssn. He moved and I can't get ahold of him. The state wants my federal return and documents supporting the charge. I don't understand what I did wrong. I didn't even get any credit because I didn't have any taxes owed.
