Can't figure out how to add a 1099-NEC to an existing self-employment Line of Work

I am on the the self-employed work summary screen and it shows my side business, along with the amount I made last year. For this year it still says $0, as I haven't entered my 1099-NEC income yet. When I click "edit" it shows me attributes for the line of work, but no option to add income for 2025. If I click Add Another Line of Work I can add 1099s, but I don't want to add another line of work  —  I want to add income to my ongoing line of work. The onscreen help is directing me to pages that don't exist. 

 

How do I add 1099-NEC income to an existing line of work?
