"What I want to be able to do is when a Task is completed in the Child board automatically update the same Task of the same name in the Parent board."
I guess your flow trigger is "When a task is completed". And, the way to match Child Task and Parant task is the name/title, right?
If you add 'Get a task' on your local board, targeting task id from your trigger, you will get its name /title.
Hope this helps
Good job! I think your condition in the "Filter array" is correct. Please make sure you assign "Filter array" output as input for your 'Apply to Each'
