Go to Code 54, Taxes, then Ohio Cities.  If not already done, Add "Cincinnati" to the city list (left side, middle pane). 

Once added, the 2nd box is "Part Year Resident".  Add the date TP moved in.  As for "First Year Filer", scroll down the same screen to "CIncinnati" (Just above Income subsection).  First box is First Year Filer is first box.

Also, as an aid, on the actual Cincinnati form, put your cursor on the area you cannot find, right click, and often it will take you to where you need to go.  In this case, both will take you straight to those entry locations. 

Good luck.
