Condonation

Respected Expert,to file a ITR of F.Y.2019-20 after due date with penalty there is a need to send condonation request.But I am not able to submit it online.Please tell me the procedure or alternative way.
Due to arrears, the income is nearly 20 lacs and a tax relief under section 89 (1) has taken but not filed ITR and hence 10 E form also not submitted.Due to this,to avoid future complication my staff member want to file the ITR with penalty.
