After you file

ok so per this from that document, he would be a qualifying child right?  :

 Child of person not required to file a return.
A child isn't the qualifying child of any other taxpayer and so may qualify as your qualifying relative if the child's parent (or other person for
whom the child is defined as a qualifying child)
isn't required to file an income tax return and either:
• Doesn't file an income tax return, or
• Files a return only to get a refund of income tax withheld or estimated tax paid. 

 

So how do I get turbo tax's program to acknowledge this without me putting him as my own nephew in it. I mean, he is listed under his uncle (my fiancee) so would it then be that he is his nephew?
