it was more difficult this year to interest income....the button add/edit but you couldn't edit per se, without adding a new income source and deleting the exisitng (last year's) income source. also, it would be easier if some rather than typing multiple charitable contributions, property taxes, etc, there was an initial summary question, showing the standard deduction amount, then asking the user if they believe they have enough deductions to exceed the standard deduction, in a simple yes/no. if they answer no, then automatically the standard deduction is used.
