Details to submit while filing rectification

Hi,

For AY 2020-21, I was given demand notice u/s 143(1) post which i realized that when i filed my original on 20th Nov'20. i realized my mistake of not paying the Advance Tax and hence paid the Tax plus Interest on 5th Dec'20 but didn't file any revised ITR claiming the Challan amount. Now i want to file a rectification in order to complete processing of my ITR-1 of AY 2020-21. I have below queries while filing Rectification for Tax Credit Mismatch Correction by using XML file in Java Utility tool -
1. Under Filed u/s, which option should i select - "139(1): On or before Due Date" or "139(5) : Revised" ?
2. Under Receipt No, do i need to enter  Acknowledgement No of Original ITR or skip filling this field ?
3. In the last page, under Date of ITR should i fill Original ITR Date or Challan payment Date ? I think it should be Challan payment date because Interest 234B should be calculated till that date.

Request your urgent help on this.

Thanks & Regards
Lokesh
