Importance of getting a 1099-NEC as an independent contractor

I am an independent contractor who earned $27,000 from one business client in 2023 via check and bank transfer. If they don’t give me a 1099-NEC, will that be an issue? Can I just report the income in TurboTax as “Other self-employed income, cash and checks”? Is there any benefit to me to trying to get  a 1099-NEC?
