I have recently withdrawn my PF after quitting my job in FY 2019-20. I was not aware that interest on PF accounts would be taxed when unemployed. I have been unemployed since September 2019. I have already filed my returns for AY 2020-21 and I do not see any option to revise it now. I want to pay the tax due on the PF interest for FY 2019-20 along with interest and penalties. What should I do?
