    from tkinter import *

window1 =Tk()
window1.geometry("400x400")
window1.resizable(False,False)
#---------------------------------------------
def test1():
    if entry1['state'] == 'normal':
        entry1['state'] = 'disabled'
    else:
        entry1['state'] = 'normal'

entry1 =Entry()
entry1.pack()
cb1 = Checkbutton(command=test1)
cb1.select()
cb1.pack()
#---------------------------------------------
def test2():
    if entry2['state'] == 'normal':
        entry2['state'] = 'disabled'
    else:
        entry2['state'] = 'normal'

entry2 =Entry()
entry2.pack()
cb2 = Checkbutton(command=test2)
cb2.select()
cb2.pack()
#---------------------------------------------
def test3():
    if entry3['state'] == 'normal':
        entry3['state'] = 'disabled'
    else:
        entry3['state'] = 'normal'

entry3 =Entry()
entry3.pack()
cb3 = Checkbutton(command=test3)
cb3.select()
cb3.pack()
#---------------------------------------------
def test4():
    if entry4['state'] == 'normal':
        entry4['state'] = 'disabled'
    else:
        entry2['state'] = 'normal'

entry4 =Entry()
entry4.pack()
cb4 = Checkbutton(command=test4)
cb4.select()
cb4.pack()
#---------------------------------------------

def message():
    b = float (entry1.get())
    c = float ( entry2.get())
    d = float ( entry3.get())
    e = float ( entry4.get())
    
    
    label1 = Label(window1, text="1) here is what you wrote ma boy :"+ str(b))
    label1.place(x=60,y=200)
    label2 = Label(window1, text="2) here is what you wrote ma boy :"+ str(c))
    label2.place(x=60,y=230)
    label3 = Label(window1, text="3) here is what you wrote ma boy :"+ str(d))
    label3.place(x=60,y=260)
    label4 = Label(window1, text="4) here is what you wrote ma boy :"+ str(e))
    label4.place(x=60,y=290)
    
button1 = Button(window1,text="Click", command= message, width=8)
button1.place(x=20,y=200)

window1.mainloop()

The checkbuttons command is executed every time you click on it. The checkbutton takes additional options like variable a tkinter variable that is set to onvalue and offvalue depending on an internal state. Check your variable in the function and alter the entry as you desire.

update You could check the variable even in a different function like your message function.

import tkinter as tk

def message():
    if var.get():
        print(entry.get())
        entry.delete('0',tk.END)

def test():
    if var.get():#check variable
        entry['state'] = 'normal'
    else:
        entry['state'] = 'disabled'

root = tk.Tk()
entry = tk.Entry()
var = tk.BooleanVar(value=False)#tkinter variable
checkbutton = tk.Checkbutton(command=test,
                             onvalue=True,
                             offvalue=False,
                             variable=var)
button = tk.Button(text='Print',command=message)

checkbutton.invoke()
##checkbutton.invoke()

button.pack(side=tk.BOTTOM,fill=tk.BOTH)
entry.pack(side=tk.RIGHT)
checkbutton.pack(side=tk.LEFT)

root.mainloop()
