I forgot to claim my child's disability tax credit for 2017 & need to refile- when refile it puts the disability on my husbands income.Need it to change to me how?

When I filed my taxes for 2017, I forgot to claim my childs disability tax credit. I want to file to claim this, when I refile in turbo tax, it automatically puts the deduction on to my spouses return. I am the beneficiary of the benefit and need to know to get it on to my tax deductions from his? The disclaimer says it automatically goes to the higher income earner, but I am the beneficiary. Any help is appriciated.
