Rectification Request Question

Hi There,

I did a mistake in one of a return where I swap the TDS deductor  PAN and while processing of return it was processed with a Tax credit mismatch. Seems I need to file a rectification, but ITR also processed some part of refund as well. So my question is:

- if x amount is processed & refunded in account, so how to show/adjust this in rectification request?

- What is better reason to select from below reasons in picture attached?
