ACCORDING TO GOOGLE THE FIRST THING TO DO IS QUIT YELLING.

Then google "Electric Vehicle Recharging Station federal tax credit how to claim" 

About the 3rd or 4th link I got was to the IRS with reference to a form number.

I have never had this credit so I don't know how the form works, but that should get you on the right track.

side note - I think dkh may have the link for the credit on the vehicle not the charging station.
