Patricia, 

Under the new law, a taxpayer who holds an applicable partnership interest will recognize net long-term capital gain with respect to such interest only if the taxpayer has held the interest for at least three years. If the three-year holding period requirement is not met, the taxpayer’s net long-term capital gain will be treated as a short-term capital gain, notwithstanding Code section 83 or any election made under Code section 83(b).

You did not mention if your taxpayer has held the partnership interest for more than 3 years. If they have, then I don't think you need to reclass the $58K from long term to short term; however, if they have held their interest less than 3 years, then you would reclass to short term. 

Hope this helps.
