Hey - yes I have a 2FA wallet. I imported my private key to a new electrum wallet and now that private key is assigned a "1" address.. which doesn't display the amount of BTG I have available like my "3" address does.... since the private key is now assigned to a "1" address does this mean that I'll be able to recover the BTG since the private key is also associated with the 3 address or does this not work?
A 2FA wallet? Excellent, that makes things a little bit easier 
Like I said earlier... you cannot simply export a key from an Electrum MultiSig address (Electrum 2FA wallets are a fancy type of MultiSig)... it just doesn't work like that.
- MultiSigs are made up of several keys (2FA's are made up of 3)
- You need to get all the individual pieces (Electrum will only give you 1, by clicking "export private key"). This requires digging around in wallet files and using various tools to convert the redeem script into individual addresses and using xprvs to find the private keys for those individual addresses
- Once you have all the pieces, you can use them to manually create a "raw" transaction.
- You then sign the raw transaction using the individual pieces that you extracted and you can broadcast the message.
