I once send Eth from my poloniex account to my myetherwallet and after that I see 0 balance so I tried to search enter the TX ID and it says that "transaction not found."
Transaction Not Found: This transaction cannot be found in the TX Pool of the node you are connected to. However, it could be in a different TX Pool, waiting to be mined. Please use the dropdown in the upper-right to select a different ETH node (e.g. ETH (Etherscan.io) or ETH (Infura.io) or ETH (MyEtherWallet)) and check again.
I tried to search the transaction in those given websites but unfortunately the " transaction not found" text is the only thing that appears.
So I'd waited for it for hours since I asked other people why does it take so long for my eth to arrived and they say that it might be because of the low fee but I didn't said about my transaction that can't be found. At the end, I received it.
So I suggest for you to wait a little longer. Just make it sure you input the right address. It might just be a case of low fee and it will confirm in due time or maybe go back to your wallet once the system had forgotten it like in Bitcoin.
I'm no expert on how does the Ethereum transactions works since I rarely use it so what I shared to you is just based on my experience and understanding. I hope it helps.
