457B transfer from one company to other

I moved my 457b from my previous employer to my current. The previous employer classified it as non-qualifying  at the time of withdrawal and deducted federal and state taxes and sent me a check  and issued a W-2 showing the tax deducted. I deposited the check into my new employers qualifying 457B plan and have a letter from the current employers plan administrator stating the entire fund was deposited into a qualifying 457B.  How do I enter the W-2 in turbotax to claim the refund of the tax.
