Yes, dmhands is correct. Also, if you did not file 2019 until very recently, the 2018 tax return would have been used. If your dependent was not on the 2018 return, that could also explain why.
While this will be corrected if your dependent qualifies, the correction would be done on the 2020 Tax Return, due April 15, 2021.
