Here is the recommended description information from TurboTax, but you certainly can use the stock symbol instead of the long name.
Enter a description of the investment sold. A broker may provide a description in Box 1a of Form 1099-B or equivalent. If this is a security normally sold in shares or units, we recommend including the number of shares/units in the description.
For example:
- 20 shares of XYZ Company
- 100 shares of S & P Index Mutual Fund
