Can't import BIP32 key into electrum
It looks like in some places you're using testnet addresses (tprv.., m..) and in other places you're using mainnet addresses (xpub.., 1..). If your software is expecting one and gets the other, then you'll likely have some problems (like Electrum not letting you click 'next'). Check to make sure all the software you're using is configured to give you the desired outputs.
