Online Version Unable to Enter Trust Final K-1 Code 11B and 1040 Schedule 1 line 24z for line 26

Help!? Please! The online TurboTax Premier version directs me to manually enter my K-1 code 11B amount as a beneficiary of a  trust (the trust closed out and this is the final trust tax filing so I have been advised that Sec 67(g) allows an adjustment to income shown on the K-1, box 11B. After an hour on the phone with TurboTax rep., there appears no way to enter this and the TurboTax populated forms state right on them to manually enter the 11B amount, but, there is no way to enter it with the online version.  If I enter a negative number into other income as advised by the TT rep., I can produce the right adjusted gross income but this is unacceptable to both the TT rep. and me because it produces the income adjustment populating to the wrong line on the 1040.
