Help, Blockchain sending error. Is my ETH gone?

Please help. On 12/22, I received about $2,000 in ETH to my formerly zero balance Blockchain ETH wallet. I then sent the entire balance to my Coinbase ETH wallet (to be exact sent $2176 and gas fee $10.47). This shows up in my Blockchain “activity” as still “pending”.

Here is what doesn’t make sense: When I put in the Blockchain ETH wallet address I sent from in etherscan.io I see a “transaction hash” from 12/22 for roughly the same amount (not the same though. It’s $2239 and transaction fee of $3.73). The address for this is NOT where I sent it to though (again, I sent it correctly to my Coinbase ETH wallet which is confirmed in my”activity” log in Blockchain. The one that shows “pending”). This strange transaction in etherscan.io also shows status as “success” as opposed to “pending”. Finally this ETH wallet address on this transaction hash where I didn’t send to is “like a master account where etherscan.io has all transactions” according to the Coinbase rep I spoke to (I called Coinbase too and they told me this and also that I need to contact Blockchain and the guy said he has no idea what happened).

Does this all make sense?

TLDR: Scared I lost my ETH and my Blockchain app “activity” correctly shows my “pending” transfer but etherscan.io shows a different successful transaction to a wallet I never sent to.
