currently the mailbox is not ready for mail to be delivered there how do i go about having my mailed forward there?

You can arrange for your mail to be forwarded to wherever you want on the USPS website. I think it’s USPS.COM. Or USPS.GOV

You could use a P.O. box until its ready, butmi eouldnt count on USPS at all. In the past 4 months I've lost over 200 from packages being lost and stolen. The.post office don't care at all, make sure you do whats best for YOU cuz USPS DEFINITELY DOES NOT CARE
