So that list is there forever, and it cannot be gotten rid of unless I download a whole new wallet copy?
If that is the case I will have to be careful of what I type in there for comments.
If you're very careful, and you don't care about keeping any bitcoin addresses that you currently have in your wallet, there is a way to remove all transactions from your wallet without re-downloading anything.
Create a backup of your wallet (let's call that backup_1).
Be very careful to store backup_1 somewhere that you won't accidentally erase, lose, or overwrite it.
Shut down Bitcoin Core
Delete the wallet.dat that is in the bitcoin data directory
Start Bitcoin Core back up
Bitcoin Core will generate a new wallet.dat with new bitcoin addresses and no transactions at all
In the "Receive" tab, choose "Request payment" to get a bitcoin address from this wallet.
Save this bitcoin address somewhere that you won't lose it.
Create a backup of your wallet (let's call that backup_2).
Be very careful to store backup_2 somewhere that you won't accidentally erase, lose, or overwrite it.
Shut down Bitcoin Core
Replace the wallet.dat that is in the bitcoin data directory with a copy of backup_1
Start Bitcoin Core back up
You will see all your old addresses and transactions again.
Create a new transaction sending your entire balance to the address that you created and saved earlier in these instructions (be sure to include a good transaction fee)
Wait until the transaction has 1 confirmation
Shut down Bitcoin Core
Replace the wallet.dat that is in the bitcoin data directory with a copy of backup_2
Start Bitcoin Core back up
Wait for it to establish peers and synchronize
You will have a wallet that has only 1 transaction received (and none sent) and your wallet will have the entire balance that you sent from backup_1 in that transaction.
Note: If you make a mistake and accidentally lose, delete, or overwrite your copy of backup_1 or backup_2 at the wrong time, it will be possible to PERMANENTLY lose access to ALL bitcoins that you had. Nobody will be able to help you recover those bitcoins. They will be gone forever. If you choose to follow these instructions, please be VERY CAREFUL.
