I have done some exploration in blockchain.info and found this details into my SegWit address:
it has a Hash 160 associated (as do all bitcoin addresses)
When I click on this Hash 160 code I get to another bitcoin address. Could it be this is the original address I used to generated my SegWit address??
I have not found a way to discover my original address from which I generated the SegWit one.
If by hash160 you mean the private key, then importing this into any wallet (such as bitcon core or electrum) will generate your legacy address (under normal circumstances).
Generally from my understanding the segwit address is merely a legacy address but with a 3 instead of a 1 (in most regular cases)
