If you received a K-1 with a box 13D deduction, you will need to contact the issuer of the K-1 and ask for their form 8283. This is annoying, and a change from 2022. If you look at the 2023 form 8283 instructions, you will see that passthrough entities (s-corps and partnerships) are now supposed to give a copy of their 8283 to their investors along with the K-1.
