I am working on my taxes - and it appears the software is automatically importing my Solana address transactions. Is there a way I can stop this?

In order to get the information correct, I have to pull some of the transactions with the software automatically, and I have to pull other parts (NFT trading, staking etc) from another software and import the CSV information.

It messes me up to automatically import, how do I stop this? I don't want it to import transactions again, it needs to be manual.
