Ive tranfered many times this is the first time this has happened, i dont know if its stolen tho because if they had my private key why hasnt my account been drained? Only my incoming transaction has gone missing im confused?

Its not stolen. Coinbase works by keeping a record of your balance in their OWN private database and send the central funds to their own wallet. This is how online wallets/service function.

It is 100% the right recieve address but theres no record of it on my coinbase that is was ever sent its not even pending

If its on the Blockchain, you are probably fine. I don't think CoinBase has gone scam after so many years.
