Entering a 1099 NEC as an expense

I have two questions. I own my own real estate company and issued a few 1099 NEC's. this year and last year. Last year I accidentally used my income minus the sent 1099 NECs because I didn't see a place to add this expense. I assume I need to amend last year's taxes? I realized my mistake this year, but cannot find a place to enter the 1099 NECs that I sent out. Do I just add them as a misc expense?
