there is lot of problems are being seen for mismatch of 26 AS and oltas of IT department . please confirm from CPC and write about it if a challan is available in 26AS why it is not coming in OLTAS of income tax department

Thank you everyone for your comments.

I'm now trying to fill the excel utility available on the website for AY2011-12. While doing this, should I put the type of return as ORIGINAL or REVISED?

Also, given that it took me 6 months last time to get a rectification order, should I still file a rectification order online or I should go and meet someone in the IT department to have this resolved? My jurisdictional AO is "ITO WARD 14(2)/KAR/W/312/2"

I was just going through the help section on the incometaxindiaefiling website, and it states that:

"Assessees having paid demand are filing for rectification to get a nil demand rectification order. This is NOT

NECESSARY." (https://incometaxindiaefiling.gov.in/portal/downloads/Common%20Errors_Efiled%20Rectification.pdf)

Given this, and the fact that my tax credit shows up in Form 26A/S, is it still advisable to go for rectification?
