I just had this same problem for the 2024 Business version. I tried saving and quitting, but that did not fix the problem. However, I played around with the software a bit, and finally got it working again. I tried two things - I don't know which one lead to the problem being resolved. 1) I went back to BUSINESS INFO and just re-clicked the set-up info for each property, and 2) I added a new dummy real estate asset.
Afterwards, I was able to add rental expense data for each property. When I was having the software problem, I could only add revenues and it would skip over the expense section. Interesting note - the problem started after I was able to enter expense data for two properties, but for the second property I added a new capital asset that needed to be depreciated. After doing this, I experienced the expense skipping problem.
