GSTR2B matching and blocked credit

hi , I am akash,
I have a doubt in claiming ITC As per 2B matched with books

lats assume a case
*ITC as per books 100 and 120
*ITC as per 2B is 100
*blocked credit calculated as per books =18 for 100 and 20 for 120


* while I am claiming ITC on GSTR 3B , I PROVIDE THE AMOUNT OF 100( I.E MATCHED)

so , what about blocked credit , whatever I have to put to whole amount (18+20) or (only 18 w.r. to invoice) is my question❓

if I have to put blocked credit (only 18) ,I will provide inleligle in PL AS LESS AMOUNT ( Accrual principal is violated)
