No additional info is needed for federal 1040. some states may allow the deduction in which case additional info may be need in the state return. if you do have a resident state return- please provide its name and someone may be able to help you further.
not sure what you're saying about prior year is correct because I checked 2023 1040 partner k-1 item 13AE. no additional info required. ay least for Turbotax desktop deluxe
