Both Long Term and Short Term Capital Gains on a Sale

Hi - I did and in-kind transfer from brokerage A to brokerage B. Once the funds were at brokerage B, I made a sale. Due to the sale, my 1099-B from brokerage B was missing the cost basis and gain/loss information of the sale since the transaction history was with brokerage A. I calculated the missing information on my own with cost basis information provided by brokerage A at the time of the in-kind transfer.

 

Here is where I'm running into an issue, I imported my 1099-B from brokerage B into TurboTax. There is ONE line item for the sale made where the cost basis and gain/loss information is missing. I'm able to manually add my cost basis to that line item but through my calculation there are BOTH long-term and short-term gains associated with the sale. How do I separate the long and short term gains when there is only one line item for the sale?
