SQL Query using Coalesce and filtration !!

I have attached a spreadsheet which explains about output of this query and what we expect as output. We need unique NDC records order by Date Fill Desc and SUM(DaysSupply) based on NDC. I assume, it will be easy if an expert can view the output which i attached on the spreadsheet. Simple logic, i am missing the syntax part !!

select 		FirstName,
			LastName,
			convert(varchar(10),DateOfBirth,101) as DateOfBirth,
			Dayssupply,
			NDC,
			convert(varchar(10),DateFilled,101) As DateFilled,
			1.0 * Coalesce(SUM(dayssupply), 0) AS SumDaysSupply 
from		voeorderhistorywide
WHERE		FirstName = 'ABC'
AND			LastName = 'ABC'
AND			DateOfBirth = '02/09/2035'
AND			Datefilled >= DATEADD(DAY, -90, DATEDIFF(DAY, 0, GETDATE()))
Group by	FirstName,LastName,DateOfBirth,
			dayssupply,ndc,datefilled 
ORDER  BY	Datefilled DESC

Is this what you mean:

SELECT  FirstName,
        LastName,
        CONVERT(varchar(10), DateOfBirth, 101) AS DateOfBirth,
        Dayssupply,
        NDC,
        CONVERT(varchar(10), MAX(DateFilled), 101) AS DateFilled,
        SUM(ISNULL(dayssupply, 0)) AS SumDaysSupply
FROM    voeorderhistorywide
WHERE   FirstName = 'ABC'
        AND LastName = 'ABC'
        AND DateOfBirth = '20350209'
        AND Datefilled >= DATEADD(DAY, -90, DATEDIFF(DAY, 0, GETDATE()))
GROUP BY FirstName,
        LastName,
        DateOfBirth,
        dayssupply,
        ndc
ORDER BY Datefilled DESC
