Please clarify your situation. Are you talking about the third stimulus? If so, I as understand it, you received a third stimulus check for yourself, but it did not include the $1,400 payment for your daughter.
Was she a dependent on your 2019 and 2020 tax returns? Did you get the first and second stimulus payments for her ($500 and $600)? If you received previous payments for her, then the IRS should have her info.
At this time, the IRS has not given any guidance about how to report missing third stimulus payments.
The IRS says check Get My Payment? for information about your third stimulus. The app may have information about your daughter.
