You may want to try checking your addresses "manually" using the BIP39 mnemonic code converter (
https://iancoleman.io/bip39/). Create an offline copy, read the instructions at the bottom of the page...
Once offline, put your Ledger mnemonic into the tool, click the BIP44 tab and then start hunting through the addresses to see if you can find the address you sent to. It really shouldn't be any higher than maybe 100.
If that doesn't work, I'd suggest changing to BCH in the coin selection, just in case you accidentally copied a BCH address and sent to that by mistake
