Income tax return filing.

Dear sir,
I have been filed ITR for AY: 2019- 20. ITR V also has been generated , My tax liability came 240 rupees, I have also been paid tax of 240 rupees, and tax payer counter file also generated (challan 280) , but the same amount which I paid as self assessment tax, is not reflecting in ITR V/ Acknowledgement.
In acknowledgement it is showing tax paid INR 0. I have downloaded ITR V with copy of Challan showing tax paid.
I have not sent my ITR V yet,. What should I do now.
please provide solution quickly.

Thanks.
