based on what I see on explorer, is this your tx sending 0.156 BTC to Bittrex

if my guess is correct, then your address 17tv6veEu... is a change address

if you could try again using iancoleman tool,
- enter your 12 seed phrase in BIP39 Mnemonic textbox
- scroll down and (on BIP44 tab) check if those addresses shown existed in your bc.info wallet
- if it is true, scroll back up a bit and change "External / Internal" to 1, this will list all change addresses
- as far as I know bc.info uses BIP44 Derivation Path (m/44'/0'/0'/0)

but if that doesn't work, try one more time
- click on BIP32 tab
- next to Client label click on the dropdown menu and select "blockchain.info"
- scroll down and check if those addresses shown existed in your bc.info wallet
- if it is true, scroll back up a bit and change the Client to "Custom derivation path"
- then change BIP32 Derivation Path to m/44'/0'/1', check if your change address listed here
