I input two 1099-MISC of sold some stocks. Turbotax treated them as income from business or rental property and asks for Schedule C or E. Why? But it was only sold stock!

You can enter it as other income and reference sale of stock.

To enter a 1099-MISC for miscellaneous income in TurboTax:

1. Open or continue your return
2. Search for 1099-misc and select the Jump-to link

1. Answer Yes to Did you get a 1099-MISC?
   • If you already entered a 1099-MISC, you'll be on the 1099-MISC Summary screen, in which case you'll select Add Another 1099-MISC
   • If you need to edit or delete a previously entered 1099-MISC, select the appropriate button

To exclude it as business income, say NO to the questions regarding the intent to earn money and that it involved work like your main job.
