"Can I use my TurboTax software to file my taxes as Trustee for my mothers estate?"
In order to prepare a 1041 for an estate (or trust), you will need to purchase a copy of TurboTax Business.
See https://turbotax.intuit.com/small-business-taxes/
Note: TurboTax Business must be installed and run in a Windows environment; it is not available as an online product nor will it run natively on a Mac. Further, you still need a TurboTax personal income tax preparation product since TurboTax Business is not capable of preparing individual income tax returns (it can only prepare returns for entities).
