You don't need to enter the items individually if you sold them all at a loss. You also do not need to fill out a 1099-B. I advise you to delete what you entered in the 1099-K entry, self-employment, and investment entry if they appear.
Here is how to report personal items sold with no gain in TurboTax Online:
- Within your tax return, go to the magnifying glass icon on the top right, type 1099-K and select the Jump to 1099-K link in the search results
- Choose Add a 1099-K
- The next screen will ask "Which type of income your 1099-K is for?" choose Personal item sales, then Continue
- Enter the information from your 1099-K
- After you choose continue, the next screen will show "Personal Item Sales". Here is where you choose "All items were sold at a loss or had no gain"
