Tax Payable queries

Hi Team,

I have filed the income tax return for AY 2021-22(FY 2020-21) and my total tax liability is like 145614 (D11 column of ITR) and I have paid 145610(D12 column). Somehow I didn't notice the difference of 4 rupees but total tax payable column is also showing 0 . Do I need to file revised return for difference of 4 rupees. 

Although, in ITR it is clearly showing there is no tax liability.  please refer the screenshot and kindly suggest.
