Siblings inheritance filing

Hi,

 

My wife and 2 other siblings have received inheritance from their parents house sale after their passing in 2025. How do I enter the share received? Total sale price was 1.9M, received after fees, 540K, the rest was split between the other 2 siblings.

House was in California. Does this need to be reported? What forms (fed and state) would i use to enter wife's part received?

 

Thanks

 

Nick
