On my mac I cannot see the 'make payment' button for e-filing. It is off the bottom of the screen. What can I do?

Try holding down the "Command" button and hitting the "minus" sign (hyphen) on your keyboard. This should effectively "zoom out" and let you see the button. 

That unfortunately did not work. After 15 minutes of wrestling I was able to simultaneously scroll up and quickly click in the region of the button and it finally went. I had to reposition the dock in order to even attempt this and it took many, many tries and swearing before I was successful. This is an amazing bug in TurboTax. The 'browser' payment window that comes up is only resizeable in an horizontal fashion. If I were able to resize it vertically perhaps it would have allowed a normal scroll to get to the button.
