If you are referring to Social Security Disability income:
You should
not enter a dependent's Social Security benefits reported on a SSA-1099 on your
tax return.
If the
dependent earned no other income during the tax year, the income is not taxable
or reportable and thus a tax return is not required.
If the child has enough other income to be
required to file, then he/she should report the Social Security on his/her
return.
