I set up 2FA on both, thanks....

1) You speak of a 'shared wallet'.  I'm simple minded....does that mean it's in their wallet or mine?  It can't be both.  I don't want my bitcoin anywhere but in my wallet....I'm guessing the moment I get verified data that my wallet in coinbase has a bitcoin in it I need to immediately move the bitcoin into my wallet?  If this is true then do I use the 'send money' icon as if I was sending it to someone else although it is just me sending it to me?

Thanks....
