That depends.   Are you a W-2 employee?  No---not on a federal return.  

W-2 employees cannot deduct job-related expenses on a federal return.  Job-related expenses were eliminated as a federal deduction for W-2 employees by the tax laws that changed for 2018 and beyond.  Your state tax laws might be different in AL, AR, CA, HI, MN, NY or PA.

If you live in a state that lets you deduct job-related expenses, the information will flow from your federal return  to the state return, so enter it in Federal>Deductions and Credits>Employment Expenses>Job-Related Expenses

If you are an independent contractor you can enter business expenses on a Schedule C.

If you are a W-2 wage employee you cannot deduct any employee business expenses on a federal tax return due to the changes in the tax code for tax years 2018 thru 2025.
