The return will generate Form K-1. https://www.irs.gov/forms-pubs/about-form-1041

- The income, deductions, gains, losses, etc. of the estate or trust.
- The income that is either accumulated or held for future distribution or distributed currently to the beneficiaries.
- Any income tax liability of the estate or trust.
- Employment taxes on wages paid to household employees.
