I'm trying to transfer unused tuition amounts to my spouse, but can't -- the program tells me the amount to transfer is $0, however, I have no tax owing.

I have found instructions on how to transfer amounts from eligible dependents, but since I am not my spouse's dependent, these tips don't apply. Is there a software issue that prevents a spouse transfering unusued tuition amounts to another spouse? Note I have a refund, my spouse has a balance owing, and we are filing jointly.
