Celsius / Coinbase transactions UK

Describe the problem:
On a spreadsheet I have worked out my cost basis of my received ETH and BTC back from Celsius to Coinbase. My received Eth and BTC on Coinbase are classed as returned not new. I have also transerred the cost bases pertanges to the future distrubtions for any losses I may claim.

I have worked out that the Eth and Btc I was received on Coinbase was returned and not new.
I did have mainly BTC and ETH on Celsius and some alts at much lower values.

What I want to know is how to record this all correctly on Celsius and Coinbase on Koinly by creating transactions on the Celsius Wallet and editing for the BTC and Eth I received on Coinbase.

Thanks for your support.

Which exchange/wallet is this regarding?
Celius / Coinbase

How did you import data into this wallet?
CSV for Celsius API for Coinbase.

What have you tried to fix this so far?
Spend many hours researching online and watching vidoes.
