As executor, your wife needs to take two steps:
- Final a final tax return (Form 1040) for her father
- File a tax return (Form 1041) for the trust
She can use any version of TurboTax to prepare her father's final return. To prepare the trust return, she'll need to use TurboTax Business https://turbotax.intuit.com/small-business-taxes/ That program will prepare Form K-1 for the beneficiaries.
Without knowing the details of the trust and its income for the year (please don't share that information on this public forum), I cannot say whether the trust distribution you received will contain any taxable income for you. As a general rule, inheritances are not taxable income.
