Once you have filed your tax return you would need to first wait and see if your tax return is accepted or rejected. If rejected, no worries you will be given a rejection reason and you can simply make the correction and re-submit your tax return.
If accepted, you would not need to do anything further. This would confirm that you have filed your tax return correctly.
