I have received a letter from ITO for Non-filing of Income Tax Returns. It states information required for 2 transactions on TDS 92B, 1 on TDS 94C and 1 AIR-002. While I could respond to transaction on AIR-002 (though it was for a different period than stated in the query), I am not clear about 92B and 94C. I am a salaried individual and do no employee or contract any one. Can you please provide me some guidance as to what/how to address this?
