In order to ease locating page fields you can use get_pages_showing_field of PdfReader or PdfWriter. This method accepts a field object, a PdfObject that represents a field (as extracted from _root_object["/AcroForm"]["/Fields"]). The method returns a list of pages, because a field can have multiple widgets as mentioned previously (e.g. radio buttons or text displayed on multiple pages).

Identify pages where fields are used

_root_object["/AcroForm"]["/Fields"]) -> root_object["/AcroForm"]["/Fields"])?
