How do I get my money out of a crypto DeFi wallet?

Excuse me, I'm a bit confused about withdrawing funds from my crypto DeFi wallet. Could you please guide me through the process? I've heard that it can be a bit tricky, especially if you're new to this. Are there any specific steps I need to follow? Also, are there any fees associated with withdrawing my money? I'd appreciate any help you can provide to ensure a smooth and successful transaction.
