Response to Intimation u/s 143(1)

I have filed ITR-1 for A.Y 2018-19 before due date without payment of self assessment tax and tax is paid after one month of filling ITR. Now I received intimation u/s 143(1) for payment for tax.
I have already paid tax but tax challan is not disclosed in ITR because of late payment of tax and revised return time is also expired.
What should I do??
