Does my 9 year old granddaughter have to file income taxes if she has no earned income and only $194.39 of short/long term gaines? It is her SSN with me as CF.

She is only 9 years old and I started this for her 5 years ago. I had added this to my taxes for previous years. Do I need to continue to claim for her on my taxes or do nothing since she has no earned income and little unearned income and not file a claim in her number?
