Get your taxes done using TurboTax

It sounds like maybe your 1099-B form is for 1256 investments or straddles, since you say there are no dates on the form.

If your 1099-B has information in boxes 10 and 11, you need to report this information on Form 6781. Here is how to do that:

1. Select Federal from the left side menu.
2. Select Wages and Income toward the top left.
3. Scroll down/ expand the list and look for Investment Income
4. Find Contracts and Straddles and click on Start or Update to the right. 
5. Answer the first question Yes.
6. Complete the rest of the section to report your gains or losses.

If you actually do have dates on your 1099-B, but just don't want to enter them individually, you can enter your information as summary transactions in TurboTax. This will allow you to enter a summary transaction for all of your sales in the same sales category, for example - A, Short term covered.

1. Select Federal from the left side menu.
2. Select Wages and Income toward the top left.
3. Scroll down/ expand the list and look for Investment Income.
4. Click Start to the right of Stocks, Bonds, Mutual Funds, Other.
5. Answer Yes to Did you sell stocks, mutual funds, bonds, or other investments in 2021?
6. If you land on Your investment sales summary, select Add more sales 
7. On the Let's import your tax info screen, select I'll type it myself
8. Continue and select Sales section totals when prompted to choose how to enter your sales
9. You'll now be able to enter the total proceeds (sales) and cost basis, along with the sales category. Refer to your 1099-B for the amounts and category. When finished, select Continue
10. You can add additional sales totals by selecting the Add another sales total on the Review your sales section totals screen.
