You don't request BTC from your Electrum wallet's receive tab - that just gives you a QR code that someone can scan to get all the address info filled out, with the amount. To actually get your BTC, you need to login to BTCDirect, go to your Electrum addresses tab
and request your withdraw to one of those addresses from BTCDirect. Are you sure 3NN1ebK5E9HznopG7EsKkDDB3gA6h9T5HM is your address? I don't think a beginner like you would use multisig addresses.
