Which product or service you use will depend on whether you need to file an income tax return for an estate (Form 1041), or an estate tax return (Form 706). TurboTax Business handles Form 1041 and will also generate the K-1 schedules and figure out how much net income is allocated to the estate's heirs. However, TurboTax does not currently support the filing of Form 706.
