Can’t find tansaction hash for ERC20 token :( Please help

I need to find the transaction hash for a an ERC20 token (C20) I received in 2017 (18th november). It shows up in my Etherscan wallet, but I just can't find the transaction hash. Please help me, trying since ages now and I don't know what I'm doing from.

Here is the wallet address with the ERC20 token (C20):

https://etherscan.io/address/0x084a7c9178bE94ea6A12De4dbFC336A66BdA8A65

Here is the Link to Etherscan with my address and the token contact address:

https://etherscan.io/token/0x26e75307fc0c021472feb8f727839531f112f317?a=0x084a7c9178bE94ea6A12De4dbFC336A66BdA8A65

Would be so great if anyone could help me.

The token is stuck since 2017 now because I mistakenly sent it to a coinbase address instead of a real wallet, they said they can help me now finally, but need the transaction hash which I can't find.
