I checked the balance on the private key (the one with the smallest amount), 0 BTC, address never used. Then I checked it based on it's legacy public address, again 0 BTC.

I haven't checked the segwit address because I have no way to get the segwit public wallet from a private key.
To get the legacy public wallet from the private key I used the old brainwallet javascript web site. Know of any javascript sites that work offline to calculate the segwit address from the private key?
