GSTR1 submitted but not filed by supplier, eligible for ITC ?

One of my supplier has uploaded invoices in GSTR1(July-Sep 2019) and submitted but did not filed that return ,the same was showing in my GSTR2A and ITC of same was also availed by me at that time ,
Supplier have filed all later and previous GSTR3B and GSTR1 returns till date but missed filing for this quarter only . 
Due to this I was having ITC difference in column 8 of my annual return 2019-20. 
He finally filed SEP,2019 GSTR1 in MARCH,2021 after me filing annual return in Feb,2021.
Will I be allowed to keep the ITC I have availed ? or do I have to reverse it along with interest ?
I haven't received any notice from GST regarding the payment of difference in ITC yet.
