1099-B has both covered and uncovered transactions

Hi--I have a 1099B with many (20+) stock sales for which the basis is reported to the IRS.  However there is one transaction for a sale in which the basis was not reported to the IRS.  Is there any way to split the 1099 and enter the info for which basis is reported (and just report the totals) and then  enter the 1099-B info separately (report the individual detail) for the one transaction for which the basis is not reported so I don't need to send the 1099-B to the IRS.   It seems like TurboTax is saying I need to mail the 1099-B to the IRS because of the one transaction for which the basis is not reported.
