text box

I'm not sure exactly what you mean by a text box or what Premiere Elements 14 has.  Perhaps there is something in this help file that will work:  https://helpx.adobe.com/premiere-elements/using/adding-shapes-images-titles.html

Create the frame in Photoshop Elements and import it into Premiere Elements.

I think you need to figure that one out by your self.

Most of us don't have E14 installed anymore for testing.
