What are good CD rates? What bank should I go to?

I recently inherited a sum of money from a relative of mine who died last year.

I already have savings and don’t need to spend any of these money so I want to put it into a certificate of deposit for a while.

I’m new to this. My current bank offers a 9 month one with a APY of. 40%. I don’t know how often it’s compounded though.

Please help.
