Interesting, because I have my first 1040 w/ an S-Corp K-1 ready to file, and I'm not getting that diag. I would check your K-1 inputs on Screen 20 and make sure everything is in there for basis. You do need a "-1" in "stock basis at beginning of year even if beginning basis is zero." Then I would go look at forms to make sure 7203 is populating. I hope this helps.
