Share capital increase after share issue

issued shares from paid up capital without checking the authorized capital along with paid up and differential right shares size mentioned in MOA now CS asks to increase authorised capital to resolve. My query here is if we should file increase in current year or do it back dated?

Note - share issued in f.y 2020-21

This is an urgent query as needed to disclose in audited statement and auditor report before avm 30.11.2021.
