"new child?" No. You are not a new child---not sure where you are seeing that. Are you trying to say that you CAN be claimed as a dependent or that you cannot be claimed as someone else's dependent? The rule is if you CAN be claimed then you have to say in My Info that you can be claimed as someone else's dependent.
The question about whether you can be claimed as a dependent appears in My Info. Do you meet the criteria to be claimed as someone else's qualifying child or qualifying relative? If do you do, then you say YES to that question. If you do not fit the criteria to be claimed then you say NO.
