I understand how to calculate the cost basis under the normal circumstances. However, I sold that stock years ago after the merger. So my cost basis was already 'used' when I filed taxes that year. This transaction last year was a payout for a law suit settlement on the merger stock price. I didnt buy any stock, I was just awarded this amount and it came in the form of a one time purchase/sell transaction. In fact, that stock didnt exist when the transaction occurred.
I'm sure I've missed something here, but not sure how to move forward.
