user13866: 18-word phrase
I believe Coinomi was a wallet which would accept an 18-word seed phrase. There will be many others.
Coinomi lets you choose the length of your seed-phrase from a list of valid lengths: 3 6 9 12 15 18 21 24
35 random letters
Private keys are usually longer
Addresses can be 35 letters long but usually start with a digit or with bc1
See https://en.bitcoin.it/wiki/List_of_address_prefixes
Perhaps this is a passphrase for the seed-phrase - the BIP39 specification allows for an optional passphrase. Some wallets have an "option" button which may allow you to enter a BIP39 passphrase - though they may call it a "seed extension" or something else.
