The "Other items" Ctrl+E dropdown in Screen 22 is missing Code AV entirely (list jumps from AQ to AW). So passing basis through manually via K-1 line 20 is not currently possible that way.

What I found is that the standard Form 3468 approach (Screen 20, Part V Section A, §48E) actually does generate Code AV* STMT on the K-1 and prepares the support schedule framework — so the plumbing is there. The problem is that the credit percentage on Form 3468 Part V line 1b simply will not populate regardless of how Part I is completed (Q7 = Yes for under 1 MW, Q8 = Not applicable, all bonus credit questions = No). No percentage = no credit amount = nothing flows to Schedule K line 15 = nothing exports to the partner's 1040.

Has anyone successfully completed a solar ITC claim on a 2025 partnership return and gotten the credit percentage to calculate on Form 3468 Part V?

If so, what was the specific input that triggered it?

We're trying to determine if this is a pure software bug or if there's an input we're missing.
