If all the assets are in the EIN of the Trust, preparing a grantor Trust return would be a safe option to insure there are no matching issues with the IRS down the line. The grantor trust return will generate a grantor letter for each beneficiary. The grantor letters from the Trust return, with each beneficiary's share of income and expenses, would be included on the beneficiary's tax return. So for example, interest, you would report on your personal return in TurboTax, received from XYZ grantor trust then the amount from trust's grantor letter.
You would need TurboTax Business to prepare the Trust Tax return. This is a desktop program and not available online. Here is a link to the product on Amazon.
