HI, welcome to the board.
I'm not sure, but it appears from my google search that there is more than one Wizard Citation.
If that's true, then you have to do the search for the manual based on the picture on the front of the manual. Just do a search for "Wizard Citation Sewing Machine Manual". Several sites that sell manuals will come up. Compare your machine, based on the shape, where the dials are, and how many levers you think it has and see if you can get a visual match. Tia's says they have one. (The manuals are not all priced the same from site to site.)
If you post a picture of your machine someone might be able to help further.
