Based on the story, it seems he sent it to a wrong address instead of yours. Other responses here might be right that this friend of yours has a clipboard virus, but you didn't mention how close you are with your friend? I mean, how legit is he?
He maybe just take that TXID randomly from the blockchain explorer with the same amount you expecting. Scammers always do this to fool victim that they sent BTC but it's not.
Now, he seems not afraid to lose $1,000 again after this issue?
