Q. How can I check that I did in fact getting the correct NC state tax refund back?
A. You should have gotten all the NC withholding back, if you never lived or worked in NC.
Q. Should I ask my employer now to change the w-2 for the current state I have been living in (TN)?
A. Yes, even though they have bee withholding NC tax, for most of 2025. You will still need to file a NC non-resident return for 2025. TN (and FL) does not have an income tax, so there will be no TN withholding. Ideally, your W-2 should show TN in box 15; but your employer may be unwilling or unable to do that.
