I participated in Disneyland stock as an employee back in 2000-2001. Once I left company I kept the stocks, received dividends but never put anything into it. There wasn’t much. I sold most of my stock in September of 2019. The 1099-B just gives the date sold, how many shares sold and amount of uncovered proceeds. How do I figure the Cost Basis. The price per share when I sold it was $138.86. Turbo tax is asking if it’s short term or long term—how do I answer this?
