Filing child's 1099-MISC income

My 14 year old child made $6083 in Youtube channel income in 2017, and we received 1099-misc for that amount from Google. I went through the section in TurboTax which asks if I my child needs to file it but the explanation lists earned or unearned income types (wages, tips, interest, etc) that doesn't seem to match our case. Do we have to include her income on our tax return (filing jointly)? Or do we have to file her a separate return?
