Fair enough. Just make sure you stick with testnet until you are absolutely sure you know what you are doing then. Don't want to end up like the guy who made this transaction and spent 291 BTC in fees to move 0.0001 BTC: https://mempool.space/tx/cc455ae816e6cdafdb58d54e35d4f46d860047458eacf1c7405dc634631c570d

You can use a tool such as this one - https://live.blockcypher.com/btc-testnet/decodetx/ - to decode your raw transaction and check it is sending the coins where you want it to before you broadcast it.
