SQL: How do I save a query result as a new temp table?

Question

I am beginner of SQL. How do I save the query result of Part A (already have multiple subqueries using WITH clause) as a new temp table, so that I can use it for the query in Part B (because the aggregation in Part B is based on Part A)? In the end, I would like to have results of Part A and Part B separately. I've tried to solution from other posts, but it doesn't seem to work for my problem as I have multiple subqueries using the WITH clause). Thank you in advance for your help!

/****** Part A ******/

Quick'n'easy option: When you get to the SELECT part at the bottom of Part A, put an INTO expression in.

Note for these statements, I have reduced the number of fields etc and replaced with ... for brevity/clarity.

WITH DL_source AS
    (SELECT
    ... ),
DL_Session_Source AS (
    SELECT ...
    FROM DL_source)
SELECT
        LogID
        ,HashID
        ...
        ,TargetMember
INTO #cte_Visit_Record_cheunghm4532        -- Added this row
FROM DL_Session_Source;

Note that the above creates a new table - it will not insert into an existing table.

A more thorough/flexible version is to first create the temporary table, then instead of the SELECT above, make it an INSERT eg,

CREATE TABLE #cte_Visit_Record_cheunghm4532 (LogID int, HashID varchar(32), ...);

WITH DL_source AS
    (SELECT
    ... ),
DL_Session_Source AS (
    SELECT ...
    FROM DL_source)
INSERT INTO #cte_Visit_Record_cheunghm4532 (LogID, HashID, ...)
   SELECT LogID
         ,HashID
         ...
   FROM DL_Session_Source;
