Where is the textbox control?

Just now need to do some designing on a form but can’t find the textbox control I have used so many times before. It is not in “common” or bootstrap 4. Is there only the textarea control that must be resized? Please excuse my ignorance.

It’s now called “Input” in bootstrap.

Thank you very much William. I probably would not have figured it out. Textbox makes more sense to me after many years but then I am not a genius.
