Need help with a U.S. address for DS-260 – No one in the U.S.

Hi everyone, I'm currently filling out my DS-260 immigration form, but I don’t have anyone in the United States who can receive my green card on my behalf. I’ve read that this address is required to complete the form, and I’m unsure what to do. Are there any legal, safe options such as organizations or other solutions that could help in this situation? Any guidance would be deeply appreciated. Thank you!
