Will Variable Remuneration Affect My Profile During Background Screening?

Hi All,
Can anybody please explain me the difference between CTC and remuneration?
Lets assume my actual CTC is 2.8 L PA, I'm getting regular shift allowance for the past 3 years as Rs.400 per day. My New company asked me to fill the details of my salary for background verification and it is mentioned as "current remuneration". I have mentioned as 3.3 L PA in the 'Variable' field under remuneration. I did calculation based on my payslip for the past 1 year. Will it affect my profile during background verification? Will they revert back my offer? or will they get back to me for explanations.
Please reply.

- is your concern only around variable component that you have mentioned?
- They may just want to see what your variable pay may be there

Thanks for the response Nainz.
There was 2 rows to mention Fixed and Variable remuneration. I have mentioned Annual Remuneration as 3.3 L in variable field, left fixed as blank. My actual CTC is 2.8 L PA, but i'm getting regular shift allowances and I have calculated everything and mentioned as 3.3 L as my annual remuneration.
