Help needed with "Adjustments u/s 143(1)(a)" for "Schedule CG"

Hi,

I'm currently NRI.

I had incurred short term and long term CG on shares most of which I had bought while I was not NRI. I submitted my ITR 2 on time. 

Recently I got "Communication of proposed adjustment u/s 143(1)(a) of Income Tax Act, 1961." telling me that "There is inconsistency in the amounts /Totals entered in schedule CG OR Taxpayer is claiming deductions u/s 54 which are more than the amounts allowable as per the respective sections."

Further, there is "Amount in Income Tax Return", "Amount as computed" and  "Variance on account of proposed adjustment". 

I had these queries:

1. Is this purely out of error in entering data in ITR preparation software I used?

2. Rather than write detailed message here and trying to do it on my own, I'm open to utilize services of anyone who can help me prepare the response to this (ofcourse with a fee). So please feel free to reach out to me and we can talk about it.
