Dear Sir,

I filed my ITR on 6-7-2017, I also filed ITRs for my two children on 7-7-2017. Today I received SMS for refund of both my children, however I did not receive. I verified as I am not supposed to receive any refund. It appears there was a gross mistake on my part while filing the ITR. My total income was 2.37 lacs from pension and interest from other sources was 6.5 lacs which works out to 84000 tax (approx). I paid after adjusting TDS balance 20000 through challan on 2.7.2017. The acknowledgement shows a refund of 84000 which is incorrect. apparently I missed out other income while filling the ITR although tax paid was correct. Kindly advise me what action to be taken. Can I revise the ITR 

Thanks
