Thanks for your response.
The part about his eligibility is done--He lived with me for 12 months, in the USA, and was disabled. I'm the only one who supported him.
It's the question about whether I have an agreement "with the other parent" that's the problem. There is no other parent. You have to answer "Yes" or "No." Without that, they indicate that they can't calculate what deductions you're eligible for. I read all the explanations, and none addresses the possibility that your dependent doesn't have another parent.
