Not sure this helps, but if the address you used(12ngg3CB9VDvkbFDx7JKY92i9kYgDmiEaj) was a one-time address from coinbase. Then coinbase would have the would have the private key to address (12ngg3CB9VDvkbFDx7JKY92i9kYgDmiEaj), depending on their program, they should be able to sweep it again into your account.

Coinbase does change its addresses in every deposit "request" but all of the old addresses were still connected to your account.

I think I got a hint on this.
-snip-
BTW, Only OLD Coinbase addresses starts with "1"

Can you help me out with this? I am not sure what to do

I'll be honest with you, my "hint" was you might be a victim of a malware or a scam as my previous reply (2nd page) stated.

The transaction was made last August9 but check if either of your iPhone or PC is infected with a malware like HCP mentioned.

1. In your iPhone, copy an address from your Coinbase app, remember at least the 1st and last 3 digits, then paste it in any text box like Messages or Searchbox.
If the pasted add is the same, you're not infected with a clipboard hijacking virus/malware or it's not active ATM.
2. In your PC, do the same, copy an address from coinbase and paste in in a text file.
If any of it changed, that must be the cause of this.

That's to clarify the scenario, not to recover your funds.
