It sounds like you should be eligible for the Child Tax Credit, but review the list of rules for a qualifying child, from Rules for Claiming Dependents on Taxes:
- "Are they related to you? The child can be your son, daughter, stepchild, eligible foster child, brother, sister, half-brother, half-sister, stepbrother, stepsister, adopted child or an offspring of any of them.
- Do they meet the age requirement? Your child must be under age 19 or, if a full-time student, under age 24. There's no age limit if your child is permanently and totally disabled.
- Do they live with you? Your child must live with you for more than half the year, but several exceptions apply.
- Do you financially support them? Your child may have a job, but they cannot provide more than half of their own support."
If they qualify, in order to ensure TurboTax is including your dependents properly, make sure you have answered all the questions in "My Info" regarding the dependents.
Navigate to My Info, Your household, select the first dependent.
- Choose "My child", continue and be sure their name, date of birth and proper citizenship is complete.
- Continue, and answer the question about living arrangements and parents.
- Continue, and answer any less common situations, if applicable.
- Lastly, enter the child's SSN and be sure that "Not valid for employment is printed..." is NOT checked.
