Can not carry forward loss after due date - u/s 143(1)(a)(II) - AY 20-21

For AY 20-21, I filed ITR3 with some carry forward loss on 10 Jan 2021 which is the last day. Now I got a notification saying " u/s 143(1)(a)(II) Taxpayers can not carry forward the current year loss as return of income is not filed within the due date / extended due date as specified in section 139(1) of the Act".

I was thinking the extended last date for ITR3 no audit for AY 20-21 is 10 Jan 2021 on which I filed the return. Please anyone clarify whether I can carry forward loss or not. Thank You
