To enter an investment sale -

Click on Federal Taxes (Personal using Home and Business)
Click on Wages and Income (Personal Income using Home and Business)
Click on I'll choose what I work on (if shown)
Under Investment Income
On Stocks, Cryptocurrency, Mutual Funds, Bonds, Other (1099-B), click the start or update button

Or enter investment sales in the Search box located in the upper right of the program screen. Click on Jump to investment sales

If you are using the TurboTax online web-based editions you will need to upgrade to the Premier online edition to report the investment sale.  The Deluxe online edition does not support entries of investment sales.

you must also use code C so the proper tax is computed on the gain.
