Economic Impact Payment made to dependent: If my adult dependent received a payment, do I add their $1400 when reporting the amount I received?

Child was not a dependent in 2020 but was in 2021.  They received $1400 as the IRS assumed they would be filing again as a non-dependent.  I received only the amount for myself and spouse.  If I follow the instructions I'll get another $1400 - which doesn't seem right.
