I clicked wrong buttons how do I go back. I read a question wrong. Now it's saying my 2 year old doesn't qualify for a dependent. He definitely does

Go back to MY INFO---click your child's name and go through the screens again.

Make sure you have entered your child as a dependent in My Info, and that you have entered the child's Social Security number.    Careful— do not say that your child’s SSN is not valid for employment.  If your child was born in 2023 make sure you said he lived with you the whole year.  There is an oddly worded question that asks if the child paid over half their own support.  Say NO to that question.
