I think you mean that you are filing an income tax return for an estate, Form 1041. That's not the same as an estate tax return, Form 706. If you are not clear about the difference, you should consult a tax professional.
To file a Form 1041 income tax return for an estate you have to use TurboTax Business (which is not the same as TurboTax Home & Business). There is no TurboTax software for a Form 706 estate tax return.
