I have a question. if basis is $0 where did the money come from to make the distribution? it's not impossible but doesn't happen often.
Turbotax does not do basis calculations so if your basis was truly $0 before the distribution you need to enter the amount on form 1099-B worksheet. describe as (s corp name) distribution in excess of basis. type would be C -held stock short term - proceeds and cost basis not reported to IRS or type F if you held the stock long-term.
