Married clients purchased high efficiency gas furnace and want to take energy credit on Form 5695.  The only appropriate place I can see to enter the cost is the Residential Energy Property Smart Worksheet, but it says at the top of the worksheet:  CAUTION:  Do not use this copy of Form 5695 unless you are married filing jointly and both you and your spouse owned and lived apart in separate main homes.  Complete Part I of the first copy of Form 5695 for the taxpayer's main home and complete this copy for the spouse's main home.

Is there another place to enter the furnace purchase when the parties are husband and wife and living in the same main home?  I'm not seeing anywhere else on the Form 5695 to claim the credit.  Thanks.
