Lost BTC wallet

I recently created a new wallet on Electrum since my Multibit HD wallet is no longer working. I think back in 2016, I set up another wallet and moved 0.032 BTC there, since I can see that amount was sent from my Multibit HD/Electrum wallet. How can I check if I actually own the wallet that received those coins? I’m looking for a step-by-step guide. I have a few usernames and some seed words, but only six of them. I suspect these words might relate to SpiderOak, which I also have on my old laptop, but I’m not sure how to access or use SpiderOak. Thanks!

So you recovered your Multibit HD into Electrum (by using the seedphrase)? and then sent 0.032 BTC from that wallet to somewhere else? am I understanding this correctly? If so, It's not going to be an easy task to find where you sent the funds to. You can try and use Walletexplorer.com to see if it was an exchange... but other than that, there is probably nothing much you can do. A seedphrase of only 6 words is not going to be of any help either (not to recover the wallet anyway). Not sure about SpiderOak though.

Make sure clear that you imported your wallet on electrum or created new wallet on electrum and moved your funds there? Electrum seeds are 12 words and if one or two missing then there is a chance to recover the wallet via brute forcing but finding 6 missing words will take million years so there's no way to access your coins unless you have seed words or the private keys.

Just like Findingnemo mentioned, seed phrases can either be 12, 18 , or 24. Now note that this is only on the condition that you generated a standard seed phrase. That simply means that custom seeds can have odd numbers of seed phrases probably something like 13 or 17 depending on how many custom words the user added to the seed. That being said, firstly if your new address doesn't have any connection like a transaction with the old wallet then you can't track it's transactions. To monitor transactions you need to have either the public key of the wallet or an address from the wallet or Even the seed phrase. With the seed phrase you would only need to access the wallet and once successful all transactions will automatically load up. For the public key you can use either a watch only or an explorer just like you would for an address.

From my understanding, OP imported his multibit wallet into electrum to recover his fund. But the wallet was empty and there was an outgoing transaction made in 2016. OP, am I undersanding you correctly? Can you share the hash (ID) of the transaction in question? We may be able to find out where the fund was sent to.

That's exactly what he meant but the transaction wasn't outgoing. The 0.032 BTC coins were sent to the multibit HD wallet after he created it in 2016. There's no way you will have 6 seed phrases and have the privilege to import the multibit HD wallet into the newly downloaded electrum wallet. Having said that, from your explanation, I believe you don't wait for the wallet to fully sync
