i have the same problem. I have several rentals. In 2018 I think I aggregate them. This year the tt self employed did not ask any questions about aggregation, but the problem popped up after review when I got the above message. I do not have any option on aggregating or dez-aggregating my rentals, just to write a statement. How can I go back and forth to see if I have any benefits from aggregating ? One problem is that due to a missing file ( supposed to be available on 2/28 ?), I can nor e file but just mail....as a consequence of aggregating and qbi. I am not a real estate pro, the rentals are just side business. Thanks.
