Helloo everyone.. Had filed individual ITR for the FY 2018-19 on 22-09-2020 by paying interest and penalty U/s 234F, and the total income is 497870.
Its been invalidated because of spelling mistake of name in ITR and as per CBDT dept. Now while revising it says that "INVALID ACKNOWLEDMENT NO".. what should be done?

2. Should i file fresh return again? Should i pay interest and penalty again? If yes how much need to pay?
