Hey guys,
In the same vein, I made a similar mistake, but am unsure of what to do after the fact! I was going to follow the steps I've seen posted recently about going Coinbase -> Shapeshift -> Toast Wallet (converting Litecoin to Ripple), but I read many people were having problems going from Coinbase to Shapeshift and that my best bet was to send to Electrum in between. However, I made a mistake when following this and accidentally sent to Electrum as opposed to Electrum-LTC (must've downloaded the wrong one when I googled it). Now it's not showing up in my Transaction History (though Coinbase confirmed it finished). What do I do?!
****EDIT: SOLVED! I found this wonderful tutorial on youtube and it's mine again! I'll put it here should anyone come across this issue like I had:
