Dear All,

I am in confusion state, after filling the Tds return for the Form 26q,

There are few short deducations certificate which are received from our vendors like u/s197... which will be filled by showing the Deducation U/S 197 by providng the refereece numberalso. After these things  i am getting the default notice as a Short Deduction(197 Certi).I will file correction return for the same by mentioning the "A" as a Short deducations U/s 197, still i am getting the default notices for the same. 

Please help me out what i have to do to stop the default returns.
