I have a great deal of experience as a financial accountant but only started doing tax last year.

The previous CPA reported 2022 K-1 amounts from 2022 on both the 2022 and 2023 1040 part II scheduled E.  The clients actual loss from 2023 is much greater than the amount reported on the schedule E.  In reviewing I notice that in fact the same K-1 from 2022 was used to prepare the 2023 1040.  Is this just a mistake?  I am afraid I am missing something here.  If this is just a mistake it seems like something that would have been caught on review.
