I've found a few similar questions, however I'm still a little unsure what to do. I had stock in a company that filed bankruptcy and processed through a few of the steps and I thought was worthless, so I entered the data to mark it as that in a previous tax year. For 2019 I received a 1099-B now advising that it's been reported to the IRS as a worthless stock transaction.
As I declared it previously I think I entered it using instructions indicating I did not receive a 1099 at that time. Now that I have do I need to try to file an amended return for that year then use the 1099-B and file as documented for 2019?
Sincerely,
David.
