If I am reading your question correctly all the the pricing details for that particular request will be on the right hand side of the message stream with that guest. as per this screenshot.
And if it is a request or an enquiry the costs will show like this. What the guest will pay will not be shown, only the relevant dates and what you charge.....
The prices shown will be those applicable to that guest and relate to the pricing at that time.
When I contacted my last guest in the message stream earlier last week, I was looking at the cost breakdown and my initial reaction was Airbnb had made a mistake, they had my nightly rate wrong.
Then I looked at the booking date and realised the booking had been made back in Sept 2020 when I was asking $5 less a night!
The details you need should be there in the message stream Christopher.
