I have read many, many postings on this topic in the community. Several date back to 2023, there was one posted in April 2025 that doesn't apply to me. I am using Turbotax Premier for tax year 2024.
I have a K-1 with Part III box 16 checked, and a K-3, which indicates that Parts 1-4 and 9-10 apply. Early on when entering the K-3, TT asks "On your Schedule K-3, go to Part II Section 1 Line 24 go to lines A, B, and C and enter the foreign country for which you are reporting foreign taxes paid or accrued": my line 24 has an entry in line A titled "US". There is an amount in column (a - US Source), column (f - Sourced by partner), and column (g - Total). In the TT-provided dropdown, there is no "US". Many people have asked this question and the advise varies from ignoring the K-3 to manually entering it in forms mode (see the answer from @LindaS5247 that she kindly answered here).
That answer was from 2023.
In TT, I now see an entry in the dropdown called "(not applicable)". Should I use that for "US"? Ignore the K-3? Switch to forms mode and enter the K-3? Upgrade my TT from Premier?
