My grandparent's estate was settled/closed in 2017. In 2018, NC Department of State Treasurer, Unclaimed Property, sent us net proceeds from the sale of stock which was my late grandfather's. I don't believe the stock exists anymore so there was no option to re-register or reinstate. We were not sent a 1099-B (or any other sort of tax form). Is this still taxable income? If so, how/where do we report it?
