Hello,
Great question!!!
I love this link because it might explain more about self employment income and expenses. If you are contractual, then it sounds like you are now self employed. When you enter your tax documents in 2023, you will have a W2 for the salaried income and a 1099 NEC for the self employment income.
This link will show you have to enter the self employment income. https://ttlc.intuit.com/turbotax-support/en-us/help-article/self-employment-taxes/report-income-self-employment/L5wADi3xQ_US_en_US In that section you will then choose the expenses you had for 2023.
This link will show you how to enter the expenses. https://ttlc.intuit.com/turbotax-support/en-us/help-article/import-export-data-files/enter-self-employment-business-expenses-like-home/L1k6HJY4A_US_en_US
Business expenses while an employee (salaried) are usually not deductible.
