Hi, here is how you find your Ledger receiving address to upload to ZenLedger. 

When you find the Ledger wallet receiving address, you can enter that into ZenLedger under "Wallets" and select the appropriate coin from the Dropdown menu.

Also, with regards to "Inside or Outside the US" - If you are in the United States as a resident and tax paying citizen, you can consider the wallet in the US. This question generally only applies to foreign crypto exchanges like Binance or Kucoin.  

Ledger Nano S

Ledger Nano X

Ledger Live Desktop

Ledger Blue
