If you need to input a K-1 (Form 1041) that you received from an estate or trust, then you simply need to enter the information from the K-1 into TurboTax Premier.
On the other hand, in order to prepare a 1041 for an estate or trust, and the associated K-1(s), you will need to purchase a copy of TurboTax Business as well as a personal income tax preparation product (see note below).

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).
