How do I add my cell phone to my taxes, as I use it for work every day? 10 hours 5 days a week, and only a little bit on the other 2 days.

Are you self-employed?   If you are self-employed it goes on your Schedule C with other business expenses.

If you are a W-2employee you cannot enter anything about your cell phone on your federal tax 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 are preparing a return for 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
