After you file

No matter which DIY program you use it relies on your answering basic information questions correctly ... in the MY INFO section ... there is no way for any program to know if you answered incorrectly in this section...  there is no way for the program to flag an incorrect answer since all the options are potentially correct .

The program asks your marital status as of 12/31 ... only you know that answer.  Then the following screens determines the correct filing status for you to use.  Then it asks if you can be claimed as a dependent ...  all DIY programs expects the user to read the questions and click on the blue more info links if needed.  It is possible for you to be claimed as a dependent by someone other than your spouse so that is why the question is asked.
