Why does my checkout page say shipping is not available?

I’m testing out my checkout page, and it tells me to select a different address because shipping is not available to that address. These are the addresses I personally use for all my orders. Does anyone know why it’s doing this? I have my default address set for fulfillments. My market is USA. My shipping rates are calculated by carrier. I just started my site and this is my only speed bump.

Go back to your shipping settings, that means from the zones you did not add your location to be part of where you can ship to

My zone is the United States. These addresses are in the United States. Do I need to change it somewhere else?

Go and change this
