Screen 2 > check the box for Final return

Screen 12> Right below the Amount paid for each quarter enter Applied to beneficiary amount

Isit that 1041-T is used for final 1041 and not when there is tax liability for the beneficiary ?

If not a final return, Screen 12, last entry in current year estimated tax, make an entry for "Date Form 1041-T filed" (It might be a bit late now, so note the 65th day rule)
See instruction for Line 25b—Estimated Tax Payments Allocated to Beneficiaries
The trustee (or executor, for the final year of the estate) may elect under section 643(g) to have any portion of its estimated tax treated as a payment of estimated tax made by a beneficiary or beneficiaries. The election is made on Form 1041-T, Allocation of Estimated Tax Payments to Beneficiaries, which must be filed by the 65th day after the close of the trust's tax year. Form 1041-T shows the amounts to be allocated to each beneficiary. This amount is reported on the beneficiary's Schedule K-1 (Form 1041), box 13, code A.

Attach Form 1041-T to your return only if you haven't yet filed it; however, attaching Form 1041-T to Form 1041 doesn't extend the due date for filing Form 1041-T. If you have already filed Form 1041-T, don't attach a copy to your return.

Can I distribute Federal tax estimated tax applied from prior year 1041 to beneficiaries for final return?
