Are you on the Other Employment Income page? Both amounts will be totaled and put in the same place on the return, so it doesn’t really matter which one you use. But most people put tips in the top box, because it already says Tips & Gratuities there.
If you are on the page with Agri-Invest, that’s a different “Other Income” page. Use the Other Employment Income page, which you can get to by using the FIND tool to search for Tips.
