Iancoleman website won't work since it is an Electrum seed you have and not a BIP39 seed phrase. You also shouldn't go typing your seed phrase in to live websites since it could be compromised or stolen.

It sounds like you have the correct seed phrase then. Do you remember checking the box to also set a passphrase? Check the first few addresses in your wallet on a block explorer such as blockchair.com. Do you see any transaction history?
