After a few tries, I quit Turbotax on my Mac. Then I opened the saved tax return directly by clicking the specific tax return icon (not by opening the general program first). It then allowed me to download and install a 214 megabyte update at about 8:20 pm. I then was able to transmit my Massachusetts and Federal returns. Maybe this update just became available at this time or maybe I just needed to close and open the program multiple times to finally get the update.
