Does anyone understand Social Security Income?

He applied for property tax credit. Told them to cancel at last minute. Was sent two refund checks. Was told because his exe were $899. Don't understand. Didn't make sense. But she sounded almost angry. So I just hung up. He is on Medicaid and SSI. Afraid to cash the checks and put money in his bank account. Or even cash them. He doesn't need the money for the things moms elder attorney says he can cash and use for.

More details please? Is your brother on Medicaid? Why is he getting refund checks from SS? I'm sure you'll get answers with more details.
