SQL - charges and payments in same column; how to break it out - sql

Question

I have a SQL query that is pulling data from multiple tables (I have 11 joins)
There is an "ARTransaction" table which contains charges, payments, adjustments, etc. and there is a "transactionCodeID" column inside of that which describes the type of transaction.
I am trying to select a lot of data, but need two separate columns(the ones with comments above them), one for charges and one for payments. Is there a way to achieve this without using the where clause? I tried to use a nested select statement but it returned the same value for every single row (the total amount)
I am attaching the query below - thanks in advance! Also I am fairly new to data retrieval so if anything else looks wonky any other advice is greatly appreciated.
SELECT CONVERT(varchar(10),sl.ServiceDtFrom, 101) AS 'srvdate'
, f.Alias AS 'svc dprtmnt'
, CASE WHEN pc.Alias IS NULL
THEN po.Name
ELSE pc.Description END AS 'svc dept grp'
, COUNT(clm.ID) AS 'clm cnt'
, COUNT(p.ID) AS 'ptnt count'
/* 1 */
, SUM(ar.Amount) AS 'all chgs' --ONLY CHARGES (tt.ID IN(1,2))
, SUM(sl.Units + sl.TimeUnits + sl.PhysicalStatusUnits) AS 'chg units sum'
/* 2 */
, SUM(ar.Amount) AS 'net pmt' --ONLY PAYMENTS (tt.ID IN(3,4,9,10,11,12,20,21))
FROM ARTransaction ar WITH (NOLOCK)
LEFT JOIN ServiceLine sl WITH (NOLOCK)
ON ar.ServiceLineID = sl.ID
LEFT JOIN Incident i WITH (NOLOCK)
ON sl.IncidentID = i.ID
LEFT JOIN HealthCareFacility f WITH (NOLOCK)
ON i.FacilityID = f.ID
LEFT JOIN ProvOrgFacility poc WITH (NOLOCK)
ON poc.FacilityID = f.ID
LEFT JOIN ProfitCenter pc WITH (NOLOCK)
ON poc.ProfitCenterID = pc.ID
LEFT JOIN ProviderOrganization po WITH (NOLOCK)
ON i.ProvOrgID = po.ID
LEFT JOIN Claim clm WITH (NOLOCK)
ON i.ID = clm.IncidentID
LEFT JOIN Person p WITH (NOLOCK)
ON i.PatientID = p.ID
LEFT JOIN TransactionCode tc WITH (NOLOCK)
ON ar.TransactionCodeID = tc.ID
LEFT JOIN TransactionType tt WITH (NOLOCK)
ON tc.TransactionTypeID = tt.ID
WHERE i.IsReversed <> 1
AND sl.ServiceDtFrom IS NOT NULL
GROUP BY
sl.ServiceDtFrom, f.Alias
, po.Name, pc.Alias, pc.Description
ORDER BY 1,3,2

You can use CASE statements to achieve this:-
SELECT CONVERT(varchar(10),sl.ServiceDtFrom, 101) AS 'srvdate'
, f.Alias AS 'svc dprtmnt'
, CASE WHEN pc.Alias IS NULL
THEN po.Name
ELSE pc.Description END AS 'svc dept grp'
, COUNT(clm.ID) AS 'clm cnt'
, COUNT(p.ID) AS 'ptnt count'
/* 1 */
, SUM(case when tt.ID IN(1,2) then ar.Amount else 0 end) AS 'all chgs' --ONLY CHARGES (tt.ID IN(1,2))
, SUM(sl.Units + sl.TimeUnits + sl.PhysicalStatusUnits) AS 'chg units sum'
/* 2 */
, SUM(case when tt.ID IN(3,4,9,10,11,12,20,21) then ar.Amount else 0 end) AS 'net pmt' --ONLY PAYMENTS (tt.ID IN(3,4,9,10,11,12,20,21))
FROM ARTransaction ar WITH (NOLOCK)
LEFT JOIN ServiceLine sl WITH (NOLOCK)
ON ar.ServiceLineID = sl.ID
LEFT JOIN Incident i WITH (NOLOCK)
ON sl.IncidentID = i.ID
LEFT JOIN HealthCareFacility f WITH (NOLOCK)
ON i.FacilityID = f.ID
LEFT JOIN ProvOrgFacility poc WITH (NOLOCK)
ON poc.FacilityID = f.ID
LEFT JOIN ProfitCenter pc WITH (NOLOCK)
ON poc.ProfitCenterID = pc.ID
LEFT JOIN ProviderOrganization po WITH (NOLOCK)
ON i.ProvOrgID = po.ID
LEFT JOIN Claim clm WITH (NOLOCK)
ON i.ID = clm.IncidentID
LEFT JOIN Person p WITH (NOLOCK)
ON i.PatientID = p.ID
LEFT JOIN TransactionCode tc WITH (NOLOCK)
ON ar.TransactionCodeID = tc.ID
LEFT JOIN TransactionType tt WITH (NOLOCK)
ON tc.TransactionTypeID = tt.ID
WHERE i.IsReversed <> 1
AND sl.ServiceDtFrom IS NOT NULL
GROUP BY
