Deductions & credits

However i didn't claim the child i aswered all questions truthfully it then asked is the other parent claiming this child i said yes it then said i cannot claim as a dependent so just like every other page before you have the option to continue to the next page or go back i hit continue on the very next page it asked for my child's ssn at first i hit continue thinking i could skip it it gave an error message so i then entered ssn and it said non dependent eic and then went on to head of house hold where again i filed single because we agreed that she was filling hoh as well that went through no problems im wondering why after i said that i wasn't claiming our child and it said that i couldn't claim our child did it then ask me enter our childs ssn
