"I have TT Business for an estate and Trust, can I file my personal taxes using it too?"
No. TurboTax Business is only capable of preparing income tax returns for taxable entities (e.g., corporations, partnerships, estates/trusts).
You will need a TurboTax personal income tax preparation product to prepare and file your individual income tax return. Since you already have a TurboTax product (TT Business) that must be installed and run locally on a computer (rather than online), you might as well purchase a desktop (CD/Download) version of TurboTax to prepare your personal income tax return.
