Bitcoin returned?

I bought 1335 in bitcoin on Sept 2nd on coinbase the money came out of my bank account instantly. I sent the bitcoin off to another wallet and the transaction is completed and everything went through. Today Sept 5th I noticed the money was bank in my bank account with no transaction history from the 2nd it doesn'tsay money returned or even that i sent the money. On coinbase my balance isn't negative and transaction still says completed. Anybody know what happened here?
