You will need to use two TuboTax CD/Download products. These products allow you to complete more than one tax return per account.
For your personal returns for yourself and your mother, I recommend TurboTax Deluxe. This will allow you to report all your income and maximize your deductions.
For your trust returns, you need TurboTax Business.
