Do I need to enter 1099-NEC income that is already part of what I am reporting in my "Other self-employed income"?

If I keep a record of all the cash and checks I receive for income in my business (labor), in my accounting program and report all of it as "Other self-employment income" on my taxes, should I also be entering information I receive on 1099-NEC forms that I have already included in "Other self-employed income"?  That seems like double-dipping.

Simple example, just to make my point:

Received 3 checks from 3 different individuals for work I did, in the amounts of:  check # 1 - $1,550, check # 2 - $2,140 and check # 3 - $1,230.  For "Other self-employment income, I reported $4,920, to represent the sum total of all 3 checks.  I also received a 1099-NEC from just the individual that paid me with check # 2.  Is it not double dipping if I report the $4,920 as "Other self-emplyed income" along with the income on the one 1099-NEC I received that represents $2,140 from check # 2?

Sorry to over simplify and thank you for any guidance.
