Get Aggregate Data From CTE
It sounds like you just need to change your outer query to also GROUP BY the employee name:

...
SELECT
(RTRIM(LTRIM(Employee))) As "employeeName"
,COUNT(1) AS "Count"
FROM employees cm
JOIN (
        Select
        RTRIM(LTRIM(employee)) As employee
        ,SUM(DollaAmt) As "TotalDollaAmt"
        ,saleDate
        ,saleID
        FROM DollaAmt 
        GROUP BY RTRIM(LTRIM(employee)),saleDate,saleID
) As ia
ON RTRIM(LTRIM(ia.employee)) = RTRIM(LTRIM(cm.Employee))
WHERE CAST(saleDate As Date) BETWEEN '2017-01-01' AND '2017-01-31'
AND "TotalDollaAmt" &gt;= '1000.00'
GROUP BY (RTRIM(LTRIM(Employee)))
