Foreign Income from Government due to Child Birth - How to Declare, if needed?

Hello,

 

My wife and I will be filing jointly for the first time and she is a Romanian citizen now living in the USA since 2020.  She has a Social Security Number now as well.

 

My wife has been receiving monthly money from the Romanian government for the 2020 tax year because of the birth of our child in the form of child support.

 

Do we have to declare this income?  If yes, how do we do this?
