How do I recover taxes my employer took out for two states? I should have only been taxed for one.

My employer took out taxes for VA and NM for several months before I noticed it.  I moved to NM early Jan. so I should get back all the taxes paid erroneously to VA, but don't know how.  I was told to file a Form 763S (Non-resident Special Return), but don't know how to get TurboTax to do this.
