Assuming you were not a full time student in 2023 -
Was your 2023 income $4,700 or more in 2023? If so, then no one can claim you as a dependent. You would file your tax return as Single (assuming you are not legally married) and you can claim your child as your dependent on your tax return. When asked by the TurboTax program how long the child lived with you, indicate the Whole Year. You will be eligible for the Child Tax Credit of up to $2000 and the Earned Income Tax Credit.
If your income was less than $4,700 then whomever is supporting you and your child may be able to claim you and your child as dependents on their tax return. If they do claim the child, then you cannot claim the child as a dependent on your tax return. You would file your return as Single and indicate on your tax return that you can be claimed as a dependent.
