Merger with Cash to Boot

From the Broadcom purchase of VMware, I received Broadcom stock for a portion of my VMware shares and cash for the remaining shares. I did not sell any shares in the last year, and have retained the Broadcom shares I received in the acquisition. I uploaded my 1099-Bs into Turbo tax and so all shares are showing in Turbo tax as stock sales. Since I retained the Broadcom stock, I understood that only the Cash to Boot would be taxable at this time. Should I just delete the entries for the VMware shares that were transitioned to Broadcom shares or do I need to report them as a sale? If I report them as a sale, do I use my VMware cost basis and pay taxes on the gains for these shares even though I have not sold or received cash for them?
