Capital gains, losses, and 1099-B forms are all entered in the same place:
- Open or continue your return in TurboTax if it isn't already open
- Search for investment sales and then select the Jump to link in the search results
- Answer Yes to the question Did you sell stocks, mutual funds, bonds or other investments?
- If you land on the Here's the investment sales we have so far screen, select Add More Sales
- Follow the instructions and we'll calculate the gain or loss from the sale
Your total capital gains for the year minus your total capital losses result in a net gain or a net loss.
You can deduct a net loss of up to $3,000 ($1,500 if married filing separately). Any capital loss you couldn't deduct this year can be carried forward and deducted on future tax returns as a capital loss carryover.
