Ah - bad explanation on my part. [apologies]
I have the coordinates from a spreadsheet and I am busy making the Point SHP (but wanting some attribute values from underlying polygons)

        Hi, I'm doing my "once a year need to do something in python
        with QGIS" :-/ Using QGIS 3.38 and PyCharm. I have a SHP file
        with 28000 polygons. Another SHP *spreadsheet* file with 22000
        Points Both in EPSG:4326 Without using QGIS processing, what
        is the quickest way to, for each point 1 by 1, find the
        underlying polygon and read the attribute field values of that
polygon?

    Load it into postgis and write a select statement?
