Filling up form 8960 Line 7

Hi - per IRS Instructions for Form 8960 (2021) document "Other items of net investment income
not otherwise included on Form 8960 reported on Schedule 1 (Form 1040), line 8z" should go into line 7 for Form 8960. Was expecting the number from "line 8z" to flow through but it is not showing up in Form 8960. Appreciate solution/advice as it is still not resolved after spending >1hour with consultant.
