Should I pick yes for dependent disability because my daughter is Autistic the help info is to general to know which category she falls under

[Vanessa A]

It depends.  In order to be considered a disabled dependent for tax purposes your daughter must not be able to substantially engage in gainful activity because of her autism. 

 If she is able to hold a job and take care of herself, then she would not be considered a disabled dependent for tax purposes.

Do I get a credit or deduction if my child is disabled?

If your child is older than 12 and you need to pay someone to take care of him while you work, you can say he is disabled and you can still get the childcare credit on your federal return.   Or if he is 19 or older you may still be able to claim him as a qualifying child dependent on your federal return.

Aside from those things, there is no federal tax advantage to saying that your child is disabled.   Your state tax laws might be different.
