Revised return is declared as Original by Income tax department !!

Hi

as all of you aware

For AY 20-21 Last date of filing Return was 10-jan21.

I had a issue this year , that my employer didn't submitted the TDS of 5 month salary by the time 10th jan 21.

They submitted it on later date and it start reflecting in Form 26AS after due date ie from 14-jan-21.

So what I did

First I filed Original return by omitting 5 month of salary detail on last day i.e on 10th jan 21 , but didn;t verify it.

but since after 3-4 days Employer submitted TDS .

I revised the return after adding adding missing 5 month income and TDS on 26th jan -21

Since it is revised return ,  IT tool didn't showed for any fine for late filing under 234F.

But Now IT dept process my revised return only,  and it showing as Original and based on filing date 26th jan 21.

They levy addition fine of 10000rs for late filing and they deducted it from my refund.

I want to know Did I make some mistake here ??

Or what I can do to get my refund of those addition 10000rs
