Although you have it working now, you should not use this wallet long term. The reason for this is a little complicated, but essentially, since you enabled 2FA when you first set it up it is now known as a "multisig" wallet. By restoring it and disabling 2FA, instead of the two signatures required coming one from you and one from the 2FA third party for a fee, they are now both coming from you. This means you can spend your coins without paying the 2FA fee (as you have discovered), but it also means that every transaction you make uses two signatures instead of one. In essence, this means that although you will notice no difference in using your wallet, every transaction you make will be larger than a standard wallet and therefore charge you higher fees and/or take longer to confirm.
Moving forward, the best thing to do is to create a brand new wallet from scratch in Electrum. In the set up wizard, select Standard wallet -> Create a new wallet -> choose Segwit or Legacy (Segwit is also better for lower fees) -> write down your seed phrase on paper, confirm your seed phrase, and set a password. Once you have done that, you can either just spend from your current wallet until it is empty and then start using your new wallet, or you can send everything from your current wallet across to your new wallet.
