Entering the correct 1099-B information when a sale listed as Short-Term, is both Short-Term and Long-Term?

[Arkenstar]

So my 1099-B statement has some positions listed as "short-term, basis not reported to the IRS, box B checked" because the positions were transferred into the account, but the cost basis info did not transfer, and the the positions were sold within the year. TurboTax will allow me to change the holding period to Long-Term and to input the cost basis. However, a small portion of these sale does still include a short-term holding period. Can I just split the entry from the 1099-B so as to break the amount from box 1d into two amounts?

Yes, you can split the entry into two transactions to report part of the sale as short-term and part as long-term since you have the information from another source for the basis of the stock sale.
