AFAIK there is currently no way to import private keys for segwit addresses from Bitcoin Core to Electrum.
I read (and bookmarked) this 2 days ago:
In the field where you enter the private key, enter
p2wpkh-p2sh: in front of the private key.
For example, do this:
Replace "5blahblah" with your private key.
It should import the correct address
I haven't tested it yet, but if it works, I want to merit him.
The only thing that I know to get your bitcoin out from bitcoin core segwit wallet is via sweeping, but it needs a 3rd party tool
You can find the tool from this site
https://segwitaddress.org/However, I don't know if it's safe or not, but this site already been discussed here
https://bitcointalk.org/index.php?topic=2767422.25Yay! Bingo! It works in Electrum
You saved my ass from weeks of waiting
