My 1099-misc was classified as self employment on the 2023 tax return. I want to amend this because it was just paid family leave and not a buisiness.

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.  

1. On the Describe the reason for this 1099-MISC screen, enter a description of the income.  
2. Click Continue.
3. Select None of these apply on the Does one of these uncommon situations apply? screen.
4. Select No, it didn’t involve work like my main job on the Did the involve work that's like your main job? screen.
5. Select I got it only in 2023 on the How often did you get income for? screen.
6. Select No, it didn’t involve intent to earn money on the Did the work involve an intent to earn money? screen.
7. Select No on the Do you have another 1099-MISC? screen.

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.
