Sales of shares of closely-held Michigan C-Corp

I recently sold my shares in a closely-held / privately-held Michigan C-Corp that I inherited from my father in 2016.  We had an official business valuation done within a few months of his passing (to establish a cost basis).  I recently sold all of my shares for slightly less than the 2016 business valuation.  (So a small capital loss.)  What forms if any should the C-Corp send me?  If they don't send anything (it's a small family farm), how would I enter this in TurboTax?
