@Kyana Williams Your question is pretty confusing. A child can only be claimed on one tax return. If someone else uses the child's Social Security number the second return to be e-filed with that SSN will be rejected. If you are asking because someone claimed your child and your return gets rejected, then you need to print, sign and file your tax return. That way the IRS will process your return and then sort it out later. Be prepared to get a letter from the IRS someday and be ready to prove that you are the one who could claim the child.
