It notice u/s 143(1)(a) for adjustment in schedule si.

For the FY 2017-2018 We have received a notice from IT department with the notice number 143(1)(a). It says about an incorrect claim and has the following message.

"Assesse is not filling special income in Schedule SI correctly"

The short term capital gain of 109985 is mentioned in the notice, we have submitted the capital gains details while filing the ITR but looks like the Schedule SI is not filled correctly. IT website says that we have not mentioned this amount in ITR in Schedule SI.

So have we just missed filling a section? So this is just an adjustment and no tax will be applied.

Any information?

Thank you in advance.
