Just out of curiosity, how are you checking for the addresses?
Did you create a new wallet in Electrum (standard wallet, "Use a hardware device"?) and then look at the addresses generated or are you checking some other way?
Also, in your original message, you said:
... So I pressed receive on my Nano S Ledger, scanned the QR code through the coinbase app and transferred them
Where did this QR code come from exactly... were you using the Ledger Chrome extension?
Also, it seems like the coins are still in that address, so i wouldn't give up home just yet
