You will need TurboTax Business to file a return for a trust (Form 1041).  Home and Business is for Schedule C filers for Form 1040 and the appropriate trust forms are not a part of this program.

Unfortunately, this program is a Windows only program.  You could try using emulation software such as Parallels for MAC (some people do report successfully running the program with this software), but we can make no guarantees that the program will work running with that type of set up and you will not get tech support if you do.
