Filed same return twice by mistake

I've filed twice by mistake... How do I remove the second version?

What changes did you make between the two submissions?

I removed the bad debts amount because I'm having challenges getting the required documentation... but I wasn't meaning to file the amended tax return cos I still have 21 days to collect documentation. So I want to carry on with the first submission.

The only thing you can do is then Request another Correction or if you submit the documents SARS will take care of it and issue an assessment based on what you submitted.
