Disclosure: I'm a software engineer at BitGo.
Most paper wallets store a single private key and this is what you can easily import with most wallets.
However, it seems that you're holding the recovery sheet for a BitGo wallet. BitGo wallets are based on a 2-of-3 multisignature setup: BitGo holds only one key while the user holds their private key and the backup key is either held by the user or a key recovery service. This way, BitGo never is in control of the users' money, but can provide wallet services and effectuate the policies set by the users.
I would be surprised if Electrum had support to import a multisignature setup off the cuff. ;)
If you've lost access to your BitGo account, you can use the account recovery on our website. If you don't remember your email address either, you can use our Wallet Recovery Tool to sweep the wallet content to a destination address of your choice. To move the funds to your Electrum wallet, you could put one of your receive addresses from Electrum as the destination in the recovery tool.
