I only suggested this since the user reported that he moved the funds and just wants to make sure there's nothing left
He believes he moved all his coins but there is still a chance some are left at a different derivation path, aka account, or an altcoin or two.
Additionally, he might receive a transaction to an old address that is part of his Trezor wallet in the future by mistake, mixing up addresses, etc. That's why I would maintain the highest security of the seed as possible. I also wouldn't destroy it and throw it away even after I stopped using it. Just leave it somewhere for your records. You never know if you might need it in the future.
I remember I moved the funds from Trezor to Ledger wallet, but I just want to make sure like no more funds left in my Trezor, like double check.
I am not going to discuss why I wouldn't suggest switching from Trezor to Ledger if you take into account everything Ledger has done in recent years. That's a different topic. In that case, you can enter your old Trezor seed in your Ledger, add the coins you had, and let Ledger Live scan to see if there is anything left.
Ledger Live is different from Trezor Suite. When you open LL, it's going to show you an empty balance. You have to instruct the software to scan the blockchains of the assets you had. Did you only hold bitcoin or altcoins as well?
It's 24 words. So it is possible to import it into the Electrum wallet and see if there's still a balance available?
If you absolutely have to then you can do that. Make sure you tick the BIP-39 option in Electrum when recovering your wallet. You also have to select the right derivation path or let the software scan most commonly used ones. Did you create many Bitcoin accounts using Trezor Suite?
