did your transaction ever sync with local electrum or are you still waiting? Im having a transaction verification problem and im trying to figure if it is me or others have had similar transaction sync verification balance issues.
If it takes forever to sync (more than 20 min assuming you are on fast connection), go into your data folder, delete the header file. Restart electrum to force the app to download and rebuild blockchain headers again. Make sure you have the seed ready to restore the wallet if things fail
