As you type the seed words character by character into the software, Electrum will display the possible words based on the letters you entered. Don't worry about how many combinations Electrum shows you. Worry about selecting the correct word. Your seed is surely written down somewhere. So, go through it word by word and enter it the way you wrote it down. If you have the correct backup, correct derivation path, and a passphrase (in case you generated one), there should be no issues with recovery.

You never told us why you are entering your hardware wallet seed into Electrum in the first place. Did your Trezor break and stop working? You have removed a level of security from your seed by doing what you did.
