You can use a bitcoin wallet like https://electrum.org/#download. Also see: How to Safely Download and Verify Electrum. With that amount, I'd do it in a clean and offline device.

If we're talking about testnet, see: https://bitcointalk.org/index.php?topic=5393289.0

On another note, can I affirm that you're not in some weird situation op? just asking since scams are pretty rampant...
