What should I put for my employment gap on my job application?

I tried applying for this office job and they wanted the last 3 years of my work history, so I put my last company which I worked at from 2019 to the end of 2023, but when I tried to submit the application, it wouldn't go through because they said I need to account for the 3.5 month gap since my last job, and I'm currently on unemployment. So what the hell am I supposed to put? Should I put that I'm on unemployment, or should I just put that I still work for my previous employer. I'm not even sure how I would record the unemployment on there.
