I had received my monthly pension dues from 1/2017 in 1/2020 only as arrears. I had filed the Income Tax return for the FY years 2016-17 to 2018-19. Now how to account my pension arrears for the back period which was received only in the FY 2019-20. It is told by my office that I should file Form 10-E in the Income Tax Department for the back period arrears physically. Whether physical filing of return is allowed by the IT department nowadays. Kindly guide me as TDS is deducted on the pension arrears.
