TurboTax allows you to report a summary of your capital gains transactions if you choose not to import your trades directly from your broker or that is not available. To do that:
- In the Federal > Wages & Income > Investment Income section of your return, click Start/Revisit next to Stocks, Cryptocurrency, Mutual Funds, Bonds, Other (1099-B)
- Answer Yes and then select stocks. Select Continue and then I'll type it myself
- Enter your brokerage information
- After entering the requested information in Tell us about the sales on your 1099-B, you get to a screen that says Now, choose how to enter your sales. Select Sales section totals.
If you need to adjust the gain or loss from any of the sales sections, you may do that by selecting the box I need to adjust my total cost basis and entering the reason. If you need to adjust the gain, the IRS may require you to attach your 1099-B to your return.
