If you are entering a child as a dependent on your tax return and the child is under the age of 17, then you must have answered one of the questions concerning the dependent incorrectly if you are being asked about their gross income for the year.
Go back through and check your answers. You should have indicated the dependent is your child, that they lived in your home for the whole year. That they did NOT provide for over one-half of their own support. That there was not another person in the home supporting them. That there date of birth shows they are under the age of 17. And that you did NOT check the box labeled "not valid for employment" when entering their Social Security number.
If the answers were all correct for the child then delete the child as a dependent and re-enter.
