Hey I made a tutorial on how to recover LTC from a 2fa Multisig BTC Electrum wallet. I accidentally sent LTC from and exchange to my BTC address, this is what a did to recover the LTC. This would probably also work the other way around if you sent BTC to a LTC address. If it is not a multisig wallet just choose standard wallet instead and import your private key. Let me know in the comments on youtube if this helped you guys.
