I'm the exec for my aunt who died in Dec 2012. How do I file her final return? TurboTax had me use the T1 but the CRA rejected it saying it needs to be a T3, not in TT.

TurboTax knows the date of death and T Slips, directed me to proceed with a T1 filing but the CRA rejects it. There is no apparent T3 return option in TurboTax.
Is there a way to use TurboTax for the final return and why would TurboTax not know better?
