Can you confirm that you have created a 2FA wallet in Electrum? It should say something like "default_wallet [2FA]" in the title bar... and you should have an icon like this in the bottom right corner of the Electrum screen:

If you are getting invalid OTP, then it's possible that the Google Authenticator on your phone needs to be resynced (and/or the time needs to be corrected)... unless of course, you don't actually have the GAuth set up and you're just typing in some random OTP.
Also, 2FA accounts don't allow you to view the seed after you've finished creating the wallet. That is why it is greyed out. If you don't have that seed or the OTP setup, you're in a world of hurt. Those coins are effectively locked into a MultiSig account that you're going to struggle to get them out of

If you had the seed, you could restore the wallet and reset the OTP... if you had the OTP you could send your coins out to another wallet... but with both lost, you're in trouble
