Here's some more helpful advice to go with Dave B's.

The part you are commenting out is a query which can be run in isolation from the rest of the query. Like the main body of the query it's been written in a naive manner and can almost certainly be improved. Changing IN to INNER JOIN etc results in something like the query below, which is much easier to work with because it's far more readable (Changing IN to INNER JOIN often won't improve performance because the optimizer will probably do it anyway).
Once you've got this far, you can check out all of those string functions wrapped around your arguments which are preventing index usage.
The query looks as if it's been written without any knowledge of the data.
Remove the string functions (one JOIN at a time) and examine the results. Examine the data in the columns to see if the string functions are really necessary. Somewhere in there is a CAST to INT - check the datatype of the column to see if it is necessary.
Before you do any of this, read the recommendations posted by others.

SELECT RIGHT(RTRIM(LTRIM(r1.RAL_DROPSITE_KEY)), 6)

FROM REF_ADDRESS_LIST_FILE r1

INNER JOIN REF_ADDRESS_LIST_FILE r2
   ON RTRIM(LTRIM(r2.RAL_DS_PHYSADD_STATEABBRV)) = RTRIM(LTRIM(r1.RAL_DS_DLVYADD_STATEABBRV))
   
INNER JOIN DISTRICTS d
   ON d.DIS_PK_ZIP_CODE = LEFT(r2.RAL_DS_PHYSADD_ZIP4CODE,3)
   
INNER JOIN USER_DISTRICT u
   ON CAST(u.UDR_FK_DISTRICT_ID AS INT) = d.DIS_PK_DISTRICT_ID
   AND u.UDR_FK_LOGIN_ID = @UserLoginID

WHERE r1.RAL_DROPSITE_KEY IS NOT NULL
   AND r1.RAL_DS_DLVYADD_STATEABBRV IS NOT NULL



“Write the query the simplest way. If through testing it becomes clear that the performance is inadequate, consider alternative query forms.” - Gail Shaw
