exactly analogously to creating a new cave.
As with a cave, you will find the process a lot easier to follow if you Edit an existing entrance first.
New in 2021 are fields for the latitude and logitude (WGS84 - the same as your GPS displays). These should be entered in degrees with decimals for fractions of a degree, e.g. 42.357 (not 42 degress 21 minutes 25 seconds, or 42 degrees 21.42 minutes).
In previous decades the location of an entrance was the output of a whole lot of surveying and position fixing (e.g. see laser points). Today, the location of an entrance is available by GPS at the beginning of the process. So we have these fields to record the data. [We don't yet have the code to automatically add these to the essentials.gpx download to be used for prospecting though.]
The full list of fields is documented: the full list of data-entry fields when creating an entrance.
