Deductions & credits

I had a question on this. If 12,000 is paid to a grandparent of a child in a tax year, can this be claimed for the child care deduction? If so, would the grandparent still need to do the 1099-misc to claim the income and get the HSH notation on the 1040 form? With such a high amount, is it necessary to withhold taxes, or as a grandparent, are they exempt from SET?
