It is not included on a 1099.

If you know how much you paid for the stock that became worthless, you may report it on your return.  Here's how to enter it in TurboTax,

• In your Federal return, choose Wages & Income
• Scroll down to Investment Income (you might have to select See more income to view this topic) and Show more
• Start or Revisit Stocks, Mutual Funds, Bonds, Other
• Add a sale and answer No, you did not get a brokerage statement.  You will see the screen Choose the type of investment you sold.  Select the option for Stocks. 
• Continue through the interview, entering your data, until you reach the screen Do Any Special Situations Apply to This Sale?
• Choose the radio button for "Worthless securities" and Continue to complete the interview.
