I have received a final k-1 and lost my entire investment

The initial investment ($12,500) in the real estate partnership was in 2008. It has done poorly since the get go. I have had negative real estate income each year until 2023 when I had a net section 1231 loss of $-15,522 and other income of $10,274. My beginning/ending capital account in section L was $7,501 and $794, respectively. This year I received a final k-1 with -$794 in rental income. I want to take advantage of the collective loss now that it is "dissolved". Can someone walk me through that? Thanks so much in advance.
