@moosebegab You could try contacting your state's health insurance assistance program.
For example, here in Oregon the group is called SHIBA. Here's their website:

SHIBA volunteers were helpful when I first got on Medicare 20+ years ago (I qualified due to disability, not age)
I'm pretty sure each state has one of these groups but I'm not sure how good they are in different states.
