problem with form 5695 residential energy credits.

My e-return was rejected because of a problem with form 5695. The error code from turbotax states that an address must be entered if checking "yes" for energy property tax expenditures.  I checked "yes"  line 21a and 21 b regarding energy property expenditures, but when asked to enter my address, the form is grey and no address can be entered. I'm using the desktop Mac version.
