We received a 1099B from the state of Wisconsin for unclaimed property from my wife's step father. We didn't know it was there prior to 2019. How do I enter the information into the Federal forms and is it taxable. When I looked at the 10099B form, it asked the broker's name. We don't know who it was as this was issued by the state of Wisconsin. Can you assist how to decalre the money?
