I am having the same issue. Getting Error: Box 12 Code G is not supported for Qualified Conservation Contributions or any other 100% Charitable deduction. The program allows for up to 60% of income for cash contributions or 50% for non-cash contributions.
Since I have already filed by Business Taxes with the K1 with Box G amount at 100%, not sure if the workaround will be valid? Why isn't TurboTax fixing this issue with priority? It is now 1 day before tax filing deadline and I can't get this to work. Turbox Tax should do better than this for its loyal customers or they'll find alternative ways to file taxes?
