I received a 1099 k for selling personal items on ebay. How do I report this? Do I just a 1040 schedule 1 form?

You can follow these steps to enter your 1099-K form to report presonal item sales:

1. Choose the Federal option on your left menu bar
2. Choose Wages & Income
3. Choose Other Common Income
4. Choose Income from Form 1099-K
5. Choose the Personal item sales on the screen that references what type of income your 1099-K is for
6. Enter the information from the Form1099-K

Unless you sold the items for more than they cost to you, the income will not show as taxable on your return.
