dependent parents and Michigan tax credits

A 70+ y.o. mother has 0 income and lives alone, but gets 100% from her support from an adult daughter. When filing tax returns, the mother answers "yes" to "can somebody else claim you as a dependent", then proceeds to do her Michigan tax return where TurboTax asks her for her heating costs and real estate taxes, among other things. TurboTax shows some of those real estate taxes will be refunded, as well as a home heating credit. After she mails in her state taxes, turns out she is ineligible for either since she is (or can be claimed as) a dependent. Is the MI TurboTax edition due for an update?
