After you file

I have a more complicated issue then I see in this forum. Hopefully you can help. My wife and I each received letter 6475 showing 2021 Economic Impact payments of $2,100. We did not receive any payments from the US Treasury in 2021. We file jointly and it would be hard to miss $4200 showing up in our account. 

 What should I do? Taxes are finished except for this issue.

Thank you, Ron
