combine two Access Jet SQL queries into one

[s430]

These are two queries that I use sequentially in order to produce a limited-scope crosstab output from what would otherwise by many more columns:

TRANSFORM PackageID
SELECT Process
FROM Sheet1
WHERE Process IN ('Recovery','Extraction','Forming')
GROUP BY PackageID
PIVOT Process;

I name the above statement Query1. The problem with this query is that 4 columns are returned instead of only the 3 that I want displayed. (The fourth column appears at the far left and is headed "Process" but predictably its contents underneath are irrelevant.)
Then to limit the output to only 3 columns, I have a second query, which calls the above:

SELECT Query1.Recovery, Query1.Extraction, Query1.Forming
FROM Query1;

How can the two statements above be combined into one?

Can nest the first within the second: FROM (first query sql here) AS Query1;

Instead of WHERE clause, specify fields in PIVOT clause: PIVOT Process IN('Recovery','Extraction','Forming');
