Part of the problem is that a) CRA designs the forms, and b) CRA combines all of the information regarding "carrying charges and interest" into one common instruction. CRA does not precisely specify what should be added where. In a tax office, generally fees, and accounting expenses are put under carrying charges and interest is left specifically for interest charges. I suspect TurboTax cannot specify without specifics from CRA.
