Excluding certain tasks from a dataview list

What I’m trying to do

I have monthly meetings template for different services that each have a To-Do task list
September meeting notes example:

The incomplete tasks across all historical meetings are pulled into one sheet for easier viability
Master list of incomplete tasks:

I started to create my task list with block quotes. That way I could keep the parent task incomplete and add update notes that could be pulled into the master list. Is there a way to exclude those empty/blank tasks with the block quote from my query? Would that require a tag for each empty task?

Things I have tried

TASK
WHERE product = [[R365]] 
and !completed 
and text != ""
SORT file.ctime DESC

The and text != “” only worked w/o syntax associated to the line item task
