I got AY 2012-13 refund No 1 on 13th July 2013
I realised in jan 2015 that one TAN No of "tata motors" was wrongly filled for one of my clients.
I rectified the return with correct TAN and i got second refund in feb 2015.
You need to relentlessly follow up to update TDs return for 2K.
Once done file rectification . it is simple procedure . No need to file revised return for tax credit mismatch and reassess the return cases.
For second option that is change in data in some schedules such as 80G donations etc you have to upload revised XML.
You cannot revise the return later bcoz the due date is over. You can always file return till 31st march 2017 for AY 2015-16. You need to wait for 26AS to be updated.
