your best option.. is to never use the tron / steem interface... becasue it leaves you vulnerable... If you take your private key that they provide you, use trons own wallet -> tronlinkpro -> a phone app / or a brower plugin (use the one on the official tron website tronscan.org / ) but yea take your private key -> and import it into that wallet. then never touch the tron section of your steem just let it be... any time you need to access your funds use your tronlink wallet...

steem is not connected to tron in any way... it is just a wallet sepperate from steem that shows your balance but your private keys can be loaded in here there and anywhere as long as its a tron wallet.
