Unregistered supply

We have supplied one unregistered person. We have made the bill with GST. He paid the tax also. But my doubt is when we are writing in GSTR 3B we have to write that taxable amount in outward taxable supply i.e 3.1 (a) tile or Non GST outward supplies i.e 3.1 (e) tile.
If we write that in 3.1 (e) tile, we have to add that value in 3.1 (a) tile or not
