After you file

Dependents are entered in MY INFO when you prepare your tax return.  Since you have provided no details here about your dependent, we cannot say whether they can be claimed as a qualified child dependent or as a qualified relative.   Was this for a 2024 return?   Who is the dependent?   How old is he/she?  Was he a full-time student?   Was the dependent born in 2024?   For a newborn you need to say they lived with you the whole year.

There are two kinds of dependents---qualifying child and qualifying relative.   "Primary" dependent is not a term used.
