Do I file 1099misc or w-2 if I got paid commission on my job where no taxes were deducted from my pay the entire year?

If your income was reported in box 7- Nonemployee Compensation, on Form 1099-Misc, you will report it on Schedule C of your return. 

If you receive a W-2 reporting your income, you'll report in under Wages & Income, Job(W2).  

If you received both 1099-Misc and W-2, you'll need to report them each as stated above.
