Stock was acquired and sold on the same day. Program for 1099-B in Turbo Tax thinks this is an error and wants me to correct it. How do I proceed?

Turbo Tax highlights the Date Acquired and Date Sold boxes and inserts the message to make a correction.  My 1099-B shows the same date for both boxes.  This transaction is for a half of a share that is left over from a stock exchange that is sold to give me the money.
