How can I report Loss on my stock portfolio for deduction purposes?

In TurboTax online, you report your losses as follows:

1. Sign-in to your account.
2. Select Federal in the left margin.
3. Select Wages & Income, left margin.
4. On Your Income and expenses screen scroll down to Investment and Savings.
5. Click on the drop-down arrow if necessary to reveal more options.
6. Click Start/Revisit across from Stocks, Cryptocurrency, Mutual Funds, Bonds, Other (1099-B).
7. At the screen Let's import your tax info, you will see the option to Enter a different way.
8. Then select the type of investment.
9. Continue to enter information as prompted.
10. At the screen Now, choose how to enter your sales, make the appropriate selection.
11. Enter your stock information. 

If you are using TurboTax CD/download, the process is very similar.  Your investment losses can be used to offset investment gains, and up to $3,000 of ordinary income ($1,500 of ordinary income if you file Married Filing Separately).
