2A and 2B mismatch

sir, my 2a of april 22 has about 15 invoices which are not reflected in April, May, or june 2022, 2B. I couldn't claim ITC for these invoices. Even 4 months after filing GSRA1 by suppliers, these invoices are not reflected in 2B but they are present in 2A. How to claim ITC for these invoices. I have already filed 3B for these duration.
