[Cryptocurrency] Move my EOS into a different wallet

In 2018 I bought some EOS, when they were still ERC20 tokens. I successfully registered them on the mainnet before the deadline. I have the public and private keys for that, and the wallet address to which the tokens were transferred. I've now successfully located my account name (which seems to have been automatically generated for me).I can see my tokens are there (on [login to view URL]). I would like to unstake them and send them to a different wallet, and I can't figure out how to accomplish this. In the attempt to do this, I've already paid to have another EOS account created (different account name than the one that was automatically generated for me). I've also downloaded Scatter but when I click Setup EOS, it wants me to pay again to create an EOS account. I don't want to do that, since I am supposed to already have an account. Scatter does not give me an option to connect to an existing account. There is no "Vault" menu. I am using the latest version of desktop Scatter for Windows. I just want to unstake my EOS and move it to another wallet. I can't figure out how to do that.
