You can use TurboTax Business to prepare a 1041 for an estate (link below), but you probably would be well-advised to seek assistance from a tax professional to prepare the return (and related documents).
TurboTax Business is not available as an online product; it must be installed and run in a Windows environment (there is no Mac version). Further, TurboTax Business can only be used to prepare returns for entities; it cannot be used to prepare individual income tax returns (e.g. Form 1040).
