She got her own check? Then no you don't enter that on your return. She should not have got a check. Did she file her own 2018 or 2019 tax return? She must have filed as an independent? Wasn't she your dependent? She must have checked the wrong box on her return. If she is under 19 you can claim her no matter how much she made.
But if she got her own check and you are getting the 1100 now for claiming her that is ok. She can keep hers and you can get it on your 2020 return for claiming her.
She might need to amend her prior return to say she was a dependent. It may change her tax return.
