Generally, "72 dpi" is screen resolution. You don't want to print at "72 dpi"
because it will look like crap.
At the 240ppi Godfrey mentioned 4032 x 2268 pixels gives you 16.8 x 9.45 inches.
To get a 20" wide print, 4032 pixels is going to give you around "201 ppi",
suggesting a crop to 2016 pixels high (for a 10 x 20 print).
A good "printer" should be able to give you an adequate 10x20 C-Type print if
the JPEG quality is high enough (2.5MB file size suggests it might be just
barely), although you're going to have to crop it to get that aspect ratio.

Thanks, Godfrey. Guess I’ll adjust the size of the test print downward.
WIAI, I take it “ppi" is "pixels per inch.” Data on this image as displayed
in Dropbox indicates 72 “dots per inch.” is that the same as "pixels per
inch”?
Yes.. in this context, ppi and dpi mean the same thing. It’s a long running
confusion.
This image was shot with an iPhone 6s using the default camera app, which
saves JPG files. If I we shooting RAW with the same camera would I be able
to do larger prints?
Raw files would net more editability but no more pixels, so no.
