My husband's father passed away in October 2019. His father had been living in his deceased wife's home since her passing in 2009. The home was in her children's name, my husband's step-sister and step-brother. When the home sold in September 2020, the step-siblings wanted to share the proceeds with my husband. During the closing process, my husband did not receive a 1099 since he was not listed as a seller. My question is how do we report those proceeds we received from the sale of the home?
