Again, you
need to read (and understand) this,
especially the "How much does it cost?" section:
https://api.trustedcoin.com/#/electrum-help2FA wallets charge a "service" fee
that is in addition to "normal" transaction fees! The 2FA service is provide by TrustedCoin and they charge you a fee to use it. If you don't want to pay this extra fee, then "restore" the wallet from your seed mnemonic and when prompted select "Disable 2FA":
1. Select "New\Restore" from the menu:
2. Give the wallet a unique name like "disabled_2fa" (to avoid any confusion in the future):
3. Select "Wallet with two factor authentication":
4. Read the "disclaimer" and click next
5. Select "I already have a seed":
6. Select "disable":
7. Add a password (Optional, but recommended)
This will create a copy of your wallet that contains 2 of the 3 master private keys. This will enable you to spend your coins "normally" without needing a 2FA code and it won't be using the TrustedCoin service.
If you intend on continuing to use Electrum in the future, I would highly recommend that you create a "standard" wallet (no 2fa, no multisig etc) and then move all your coins to the new "standard" wallet. It will make things much simpler and prevent any future problems from using a "disabled 2FA" wallet.
