Amending 1040: 1099 should be line 21, not Sched C. Delete/re-enter or move?

I filed my 2017 1040 return, but just realized I mistakenly put a 1099-MISC on Sched. C that should be on line 21. 

I found the instructions on amending, my question is: should I delete the 1099 from Sched. C, and then add it to line 21? Or is there a way to move the existing 1099?
