How long do I wait?

I am 63yo and retired from working on January 4th. I applied for SS on December 26 to begin with the month of January (to be received in February). Within the first few hours I received a message stating,

“A representative in BALTIMORE MARYLAND started reviewing your application on December 26, 2024. For most people, this review takes 30 days.”

It’s been 40 days now and I have heard nothing further. How long should I wait before contacting someone? What is the best way to contact them if that becomes necessary?
