Hi guys, I am relatively new to online currencies and really screwed up when trying my hand at it for the first time. So I bought LTC off of coinbase and then tried moving my LTC to an electrum wallet. After moving the LTC to the wallet I realized that I had moved my LTC into a BTC type of electrum wallet. So, after spending a bit trying to figure out that I finally moved it to a 2-of-3 type of multisig, electrum LTC wallet but here is where the really problem starts. I lost my seed to my 2-of-3 wallet, also I cannot send any currency from said wallet because I was really excited when I saw I had my LTC back that I forgot to make a second wallet for signatures. I do not know if there is any way to retrieve my LTC back, I am still currently in full control of the LTC just unable to access the wallet seed and spend and of my coins. Thanks in advance for all the help.

Okay, I'm fairly certain it would be impossible for you to send LTC to a Bitcoin address because the address shouldn't validate. So you say you sent it to a 2 of 3 electrum Litecoin wallet? Shouldn't you have 3 keys for it then? If you've lost your keys to the wallet, it's impossible for you to recover your coins. Could you link us to the transaction or try pro provide more information?

Here is the transaction number from when I sent LTC from Coinbase.com to an Electrum BTC Wallet - c36bef2a69fa4fd14abbe98cd4f21763d9f78efccc4c20f708cb33a2774bf13a
As for transferring the LTC from my Electrum BTC wallet to my Electrum LTC wallet I followed these instruction :
        You should have mentioned this earlier. Two-factor authentication is a service provided by TrustedCoin (see here), and they do not support Litecoin, which is why this option isn't present in Electrum-LTC.
Now, the problem is that 2FA seeds are a special variety that isn't supported by Electrum-LTC (for the reason above). It should still be possible to recover the coins, I'm just not entirely sure how without writing ad-hoc code. Here is what I would try. First of all, in Electrum for Bitcoin, make a new wallet restoring from your 2FA seed, and when asked select to disable TrustedCoin. Do not enter a password. Then, close Electrum and open the wallet file you just created in a text editor. You will find 3 xpub and 2 xprv addresses. Open Electrum-LTC and create a new multi-sig wallet with a 2-of-3 scheme. Use the first xprv address and the other two xpub addresses. This should give you a wallet with the right addresses (use the converter to check).

litecoin is a fork of bitcoin and because of that they share some features such as multi signature addresses. in this case the LTC devs made the mistake of using the same version number for P2SH keys which led to both BTC and LTC having multi sig addresses start with 3. they changed it later to 50 IIRC which leads to multi sig addresses in LTC to start with M.

technically yes. but a 2 of 3 means you have 1 key in your wallet and 1 key is in that online service you use (TrustCoin?). your seed however is capable of recovering 2 keys for you, 1 which is stored in your wallet already and 1 which is not stored in your wallet nor that third party has. it is the third key.

which is why OP needs his bitcoin multisig wallet Seed to recover his litecoins in a new LTC wallet.

So w/out my seed I am screwed?

to the best of my knowledge, yes.
