You received a letter
A notice is a specific question about a specific year. The first job is to read it, not to answer it.
Bring the letter, the year it names, and anything you already sent back. We will say, in ordinary words, what it is asking and what it is not asking.
We do not guess a missing figure so a reply can go out faster. If a number is not in the papers, the next step is to ask for it.
If a response is part of the work, you read it before it is sent. The fee for that work is named in the letter we send you first.
