If your first original return was Accepted then you could not have efiled another return unless it was an amended 1040X return. I see the 1040X is available now. Maybe you were still seeing Accepted for the first return.
You should probably take out the interest and put your return back to the way it was when you originally filed. Then try amending the right way.
