If you were selling personal items, and you didn't get a 1099-K or make a profit, you don't need to include this on your return.

If you were selling things as a business, you can include the income on Schedule C. you will file a Schedule C.  There, you will list your income and expenses separately.  Since you didn't get a 1099, list the income as "other self-employed income." Here is how to do this in TurboTax Online: 

• Navigate to Federal > Wages & Income > Self-employment income and expenses > Start
• Answer "Yes" to the question "Did you have any self-employment income or expenses?"
• Give a description of the business
• Continue until the interview asks "how does your work fit into your big picture?", based on the information you provided, it's a side job and/or a business.
• Answer all the informational questions until you get to the screen  "Let's enter the income for your work."  Here, enter that you received common income- Other self-employed income, including cash and checks; then enter what you were paid.
• Once you've entered your income, type in your expenses in the proper categories, TurboTax Online will recommend popular categories, but refer to your records to ensure you are deducting all of your expenses

I'm sorry. Why did another expert say something different?

Where you report your transactions depends on the intent of the sales.

- If you are NOT in the business of reselling used clothes, these transactions would be treated as capital transactions as was mentioned on the other thread. If you made a profit, you'd follow the steps outlined in the other thread to report the income. If you generated losses, the losses aren't deductible and you don't need to report them. This would be the case if you're infrequently selling off your own personal items.

- If you've created a business of reselling used clothes for a profit, these transactions would be treated as business sales and reported on a Schedule C as Mindy outlined above. 

Thank you so much for the steps.
