I also received a private message but it did not indicate the child was a non-citizen.
It is important to determine her status. If she is a resident alien (passed the substantial presence test or has a green card) then her standard deduction is the same as a US citizen. However, if she was a non-resident alien, she does not get a standard deduction, and may have been required to file a return for the $7K wages. A non-resident alien is someone who is in the US less than 183 days, or certain students on F- or J- visas, even if they are in the US for the full year.
