I got the 3rd stimulus in march 2021 I will owe?

I got the full payment for me and my wife and two dependent children in March 2021(3rd Stimulus) . The two dependents  are no longer considered dependents for tax purposes since they used my 2019 info.  So since this is a credit will we have to pay this back  when we do taxes in 2022 

 

This also just seems like an advance from the irs not free money.  This has the potential to reduce most peoples tax refunds and in my case owing when filing taxes in 2022?  

 

Any help in this matter would be greatly appreciated.
