Is there a way to make this disabled 2FA wallet to a standard wallet besides sending bitcoins to a standard wallet?
Electrum 2FA wallet is a 2 of 3 multi-signature wallet and there is no way to turn a multi-signature address to a single-signature address.
As long as 2FA is enabled, your wallet file contains one master private key and if you want to make a transaction, you should ask trustedcoin to cosign your transaction.
If you disable 2FA, your wallet would be still a 2 of 3 multi-signature wallet, but with two master private keys.
As mentioned by Charles-Tim above, if you want your fund to be in a singles-signature wallet, you have to make a new transaction and send the fund to your new wallet.
So since there is no extra fee covering that 1 output, there are now only 2 outputs. What is the basis of the outputs? How can it be to be 1 output only?
If you want your transaction to include only 1 output, you should spend the entire balance of selected UTXOs, so that your transaction doesn't have any change.
