Query from multiple columns

https://docs.google.com/spreadsheets/d/1g7bKBV5Erd4XI8aMuDI278_g3GMbpy-f8UXqEinxUf0/edit?usp=sharing

Here is a sample sheet that has 4 different tabs with 4 columns per tab that I want to 'count' from. The final tab shows a summary of what I would expect to find in the query.

Anyone who has suggestions as to the coding for this--it would be appreciated.
