You need to enter your expenses associated with income reported on a Form 1099-NEC in the Self-employment income and expenses section, which you will find under Wages and Income. Income reported on a Form 1099-NEC is considered self-employment income so you need to set up a business in TurboTax to report it and the associated expenses: 

In that section, you will be prompted to enter your Form 1099-NEC and then the expenses associated with it. 

The section you mention is for employment expenses associated with salary income reported on a Form W-2.
