Hi,
There is no provision to add missing invoices in GSTR-1, however you can ask your customer who will be eligible to claim ITC against the missing invoice.
To explain further, approach your customer and ask him to include the captioned invoice in his GSTR-2 and once done, it will get reflected into your GSTR-1A, and by accepting the same, the invoice will get included in your GSTR-1.
