Have you installed tronlink wallet? It's easier to do transfer with that wallet, you just save all the 3 private keys on the tronlink. The transfer between the wallet can be done with the tronlink by just send to the public address of these 3 accounts you have, through send/receive button.

Or you can do that on steemwallet too. You need all 3 private keys ready for that and also the public keys too.
If you don't mind, could you share what was your problem with me? So I can help others too. Did you happen to update the Tron account after the first step of creat your tron wallet for the first time? Also, you have 3 Tron accounts because you clicked the update tron account button on steemwallet page 2 times? I appreciate your feedback so I know the reasons why others have the same issues. Thanks in advance for your cooperation.
