Need info on how to file and what expenses I can deduct with being a W-2 and 1099 employee?

ALL of your income goes on the same 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 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

Do you have a 1099NEC for work as an independent contractor?

If you have self-employment income then your business expenses go on a Schedule C.   If you are using online TurboTax you need Premium software to prepare a Schedule C.   Or any version of the desktop download software can prepare a Schedule C.

If you have self-employment income for which you will pay self-employment tax for Social Security and Medicare,  you will need to use online Premium software or any version of the desktop software download so that you can prepare a Schedule C for your business expenses.
