This is almost certainly a tcl/tk/tkinter on Catalina issue, not an IDLE issue.  Screenshots are missing headlight colors, and that should be impossible to cause from Python.  In standard python, try

>>> import tkinter as tk
>>> r = tk.Tk()

Should see small (about 2"x2") box.  If not, add
>>> r.mainloop()

And/or, try $ python3 -m turtledemo
