How can I add investment income from Box 1099-MISC to Form 8960 Part I Line 7? It is not flowing through. Per the investment prospectus the income is ordinary and not CG

I received a 1099-MISC for investment income (various structured securoties). I have been able to find out to input without triggering Sch C/self employment taxes, but the income is not flowing onto Form 8960.  Per the invest prospectus this income is ordinary income and not capital gain.
