You should not change it; enter as it is so it matches what the IRS received. If your employer gave you income not on your w-2, you can indicate that when you enter the 1099-NEC. TurboTax will generate Form 8919. All of your income received from that employer should be on your w-2 - all of it; none should be on a Form 1099-nec - you can't be an employee and a contractor to the same company.
