Be careful of popup or notifications on an old version of Electrum if you use the link from the popup notification on the old Electrum you will redirect to the fake Electrum website with the latest version of the fake Electrum wallet.
If you did it recently then I suggest you disconnect your PC/laptop to the internet right away before the fake wallet sends your BTC to the unknown wallet.
And then download the Electrum directly on the original website which is electrum.org with another PC/laptop and transfer it through a USB flash drive to make sure your PC/Laptop with the fake wallet is not connected to the internet.
Also verify the downloaded Electrum if it's the original Electrum wallet or not you can follow the guide from here
