How do I account for a difference between filing and assessment amounts on GST filing?

The report/filing was for the amount of $308.00 but the assessment gave a refund of $640.00- should I go back, undo the report- (it was a late filing for Q1 of 2023- so will have to undo the rest of them as well) revise it somehow and refile or is there a trackable way to record it without doing that?
