Many thanks to Marcos for installation assistance. My actual use of Turbotax has uncovered some interesting squirrelly behavior. For example, within the interview process I can't navigate back and forth using the drop downs. I can conduct the interview from beginning to end. The forward and back buttons don't always take me where I want to go. For example, I wanted to go back and add my wife's W-2 via the interview but couldn't. It would only let me access information about investment income. I worked around by entering the information into a blank W-2 form. Have others observed any unusual behaviors when using the app?
