So you have received the 19.82 in Bytes, that is immediately available. (hold it on your wallet until the wallets come back online and then you can transfer it to an exchange for another crypto or your can hold it), the other half is locked in a smart contract for a year. You can create another wallet on another computer but this one is specifically tied to your steem account. That is why they just airdropped you a free $20 :)
