Thank you for choosing TurboTax.

Thanks, but that won't work when you start with Forms.  If you do, going to Easy Step will grey out (locked) the Find button.  The solution in Forms for entering data in line 47600 is to enlarge the Text Size as large as possible until you see the blinking cursor when you click the cell.  It was a bad screen management by the software, resulting that the cursor is hidden when text size is small.  Hope this help others.  Took the experts (??) a couple hours to find this solution.  I am thinking of switching to a competitor after more than 15 years with TurboTax.  I am using a competitor for the volunteer work.

God bless you.
