Operand should contain 1 column(s)

Hello I have problem with this query

INSERT INTO radacct 
    (acctsessionid,acctuniqueid,username, 
    realm,nasipaddress,nasportid, nasporttype,acctstarttime,
    acctupdatetime, acctstoptime,acctsessiontime, acctauthentic,
     connectinfo_start,connectinfo_stop, acctinputoctets,

     framedipaddress,dup,t_session, nas_name,groupname,
     percent_q,down_uq,up_uq,all_tu,up_dq,dwon_dq,time_dq,t_update)
     VALUES ('80a000cc', '678593b487e8a42f68685f896b9d6d5d',

     DATE_SUB('2019-05-18 03:06:18' , INTERVAL 10934 SECOND), 
     CURRENT_TIMESTAMP(), NULL, 10934, '', '', '',

The error is due to the last two COASLESCE() function in your query:

For an example, you are expecting 3 values from the below COALESCE() function, but it doesn’t

COALESCE((
        SELECT SUM(`r5`.`acctinputoctets` * (r5.percent_q / 100)),
               SUM(`r6`.`acctoutputoctets` * (r6.percent_q / 100)),
               SUM(`r6`.`acctsessiontime`)
        FROM `radacct` AS `r5`
        WHERE DATE_FORMAT(STR_TO_DATE(`r5`.`acctstarttime`, '%Y-%m-%d %H:%i:%s'), '%Y-%m-%d') = DATE_FORMAT(NOW(), '%Y-%m-%d')
            AND r5.username = '1'
        ), (
        SELECT 0,
            0,
            0
        )),

You need to change it to individual select value, then it will work.
