If I am active duty military and PCS'd this summer and the military already reimbursed my move, do I still file moving expenses on Turbotax?

Yes, you should enter the information in case there were some expenses not reimbursed by the military.  You should have a code P in box 12 of your military W2 that shows the amount of moving expenses reimbursed.  That number will populate in the moving expenses interview from your W2 entries.  You should then enter your actual expenses in the appropriate boxes in the "Moving Expenses" topic.

You find the "Moving Expenses" topic in the "Other Deductions and Credits" dropdown menu in the "Deductions and Credits" section.
