It should not be included for input reconciliation.

While doing GSTR 2A Reco, input credit needs to be reconciled with the GSTN of parties and for the differences necessary action shall be taken i.e either to reverse the credit if not eligible or to inform the supplier to submit the same if not submitted earlier.

Since the same is not submitted by the supplier, it is buyer responsibility to inform supplier to submit the same and then the credit can be claimed later on one it is reflected in your GSTR 2A.

Thank you murali
