Yes, you need to amend. Your children's SS benefits were not supposed to be included on your own tax return.
Do not enter the SSA1099 for your child on your own tax return. Someday if the child has other income (after school job, etc.) and is filing a tax return, for that tax year he will need to include the SSA1099 on his own return. Until then, it does not get entered anywhere.

Do not expect quick results from amending. It can take four months or more for the IRS to process an amended return.
