I assume this issue is in the personal version for the 1040 return.
Under the Personal Income tab scroll down to the Business section and elect to start/update Business Income & Expenses and click the Edit button next to the business name.
Elect to update Business Income, then update 1099-MISC Income. ON that screen, you should be able to select the faulty 1099-MISC entry and delete it.
You may also need to check under the Personal Income tab in the Other Income section. Under that select Income from Form1099-MISC. If you see a 1099-MISC listed there, you can delete it. If you are prompted for 1099-MISC info, then go no further. Just click the Back button at the bottom left of the screen.
