Can you provide clarification regarding this situation around dependents?  Our daughter (24 yrs old and living with us) claimed herself for the 2020 tax year, and received the $1,400 stimulus payment last March, 2021.  During 2021, she only made $2,500, and since we provided for almost all of her living expenses, we are claiming her for the 2021 tax year.  My husband and I each received $1,400 in stimulus money in the spring of 2021.  We're filing jointly for 2021, and when we get to the place where we enter stimulus, Turbo Tax is figuring that we should have received $4.200 - I'm guessing because we are claiming our daughter.   When I enter that we only received $2,800, TT calculates an additional $1,400 credit due to us.  When I file my daughter's return (filing single and filing as 'someone else can claim me'),  in the stimulus section, it shows that she should get $1,400 back.  I enter that she did get $1,400 back, but it would seem that since we are getting the $1,400 credit, she should have to pay back the $1,400 that she received.  What am I missing?  We shouldn't both get to take the $1,400 credit for her.
