Find and Replace Checkbox and Text

Beginner here! I'm trying to use a macro in Word to find a Legacy checkbox (wdFieldFormCheckBox) with particular text beside it, in order to delete both the checkbox and the text. I was using the following to find text and replace it with nothing, but I don't know how to include the checkbox in the "Find" function.

Sub Test()
With Selection.Find
.ClearFormatting
.Replacement.ClearFormatting
.Text = "Protocol"
.Replacement.Text = ""
.Forward = True
.Wrap = wdFindContinue
.Format = False
.MatchCase = True
.MatchWholeWord = False
.MatchWildcards = False
.MatchSoundsLike = False
.MatchAllWordForms = False
.Execute Replace:=wdReplaceAll
End With
