A bill for which the E-Invoice was generated on the 11th at 3 PM, i.e., on the last date of filing GSTR-1, will take around 24 hours to auto-populate on the GST portal, meaning it will reflect only by the 12th. In such a case, if we upload that bill manually in GSTR-1, we will not be able to enter the IRN details of that invoice manually, even though the E-Invoice has already been generated on the 11th.
