jpf?? How to convert to jpg?

[Cindy Young]

I bought an refurbished computer and it runs PS2023.  I am trying to fumble my way through the editing as some parts are new.  When I "save as,"  there is no choice for jpg, just 2000jpg.  So, when I save it as 2000jpg, it ends up as a jpf.  How do I convert it to a jpg?  I am using a Mac computer.
