I am assuming you are amending your 2023 tax return with the 2023 desktop software. You will want to delete the 1099 you entered and the Schedule C that was started. Then re-enter the 1099, as follows:
Under Other Common Income, select Start or Revisit next to Form 1099-MISC. Enter your 1099-MISC info on the Let's get the info from your 1099-MISC screen and click Continue.
Answering differently to any of these questions will imply self-employment and generate Schedule C. Don't forget to delete the Sched C and the erroneous 1099.
