My 1099 B reported sales as single transactions that included both long-term and short-term sales (no basis reported). How can I split the sales into long-term short-term

[pp925847]

Specifically I need to know how I can either correct the 1099 B or just split the transaction on form 8949

You can manually input the correct entries into the TurboTax stock sales interview.  To do this in TurboTax, 

• In your open Federal return, choose Wages & Income
• Scroll down to Investment Income and Show more
• Start/Revisit Stocks, Mutual Funds, Bonds, Other
• Add a sale and answer Yes, you got a brokerage statement. 
• On the next page "Choose your bank or brokerage," scroll down and select "I'll type it in myself."
• Enter your brokerage name and Continue
• On the page "Tell us about your Brokerage 1099-B" choose the radio button for "I'll enter one sale at a time."

This will allow you to enter the correct holding period and basis for your stock sales.

Don't worry about your individual entries not matching the 1099-B. The IRS is only interested in the total, which will match.
