Interest on Advance tax

My salary is 16 lacs (monthly advance tax paid) TDs 5.5 lacs

OS income is 2.7 lacs ( 10% TDs done) 15000 tds

I also paid  self assessment tax on 29 march 20 -10000

And 65000 advance tax on 28 march 20.

But still the itar 2 shows - Interest on deferment of advance tax. Rs 2750. Is it correct. My refund is  Rs 17860.

What should I do ? Pl guide.
