The answer did not solve the problem. There is no way to enter multiple dates in the form. The Turbotax program keeps wanting to satisfy this requirement before the final submittal of the return. I solved the problem by entering the word "various" so I could finish and submit the return. During the process of figuring the taxes the Turbotax program asks for the download of the 1099-B. I did that and it was accepted. The line items requiring the dates indicates to refer to the attached statement. I can only assume that Turbotax transmitted the downloaded information with the return. No where does it show in tax documents that this was done, that I can find.
