I think I figured this out, will be great if someone can confirm validity.
In the Quickzoom, enter the section 988 gain NOT in "Other nonpassive income (loss) to be reported on Schedule E, page 2" but in the next line, which is "Other * (enter description)". This entry doesn't flow anywhere - the asterisk is explained further below in quickzoom as "Manually enter items here and on appropriate tax form or schedule".
Then I can apply @PatriciaV 's recipe: Wages & Income -- Less Common Income group -- Miscellaneous Income, 1099-A, 1099-C. -- Other Reportable Income -- enter description and amount.
This now flows to Schedule 1, Line 8z and gets included in other income
