I had the same problem. This is a HUGE problem and Turbotax should FIX it. It took me four hours to figure out how to fix this when I finally found this thread. Whoever said to go to View >hide toolbar saved me. The problem is that Turbotax opens the screens to purchase and pay for state (and other things) modally - meaning that you can't get out of that screen and that you can't interact with the Turbotax application either. Basically you can't go forward and you can't go back. SO STUPID!!
I had to ForceQuite Turbotax, then reopen the application, then go to View>HideToolbar (which got rid of the little pictures in the toolbar and moved the screen up...and then when I went to pay, the Place Order button was showing because the whole screen moved up that 1/4 inch.
TURBOTAX NEEDS TO FIX THIS. I EVEN SPENT AN HOUR ON THE PHONE WITH THEM AND THEY DIDN'T HAVE A CLUE HOW TO GUIDE ME ON IT.
