I know they don't make it easy. I think you have to sign out to get rid of the TurboTax Assistant. On the File menu on the black bar at the top left (not the gray File tab) click "Signed in as cswish2024" and sign out. Then click Search at the far right end of the gray bar near the top. If you get a window asking you to sign in, don't sign in. Click the X in the top right corner to get rid of the sign in window. Then you will have the Search box, as in the picture that VolvoGirl posted above.
