After you file

Thank you DawnC.   That works.  And I appreciate your help.  But I am also pretty frustrated with TurboTax.

 

So, if I understand correctly, I cannot complete my return entirely in the "Step-by_Step" interface but must enter the "Forms" interface to input the business use percentage.   In the past I have always been able to complete my entire return using the Step-by_Step screens.  How was I supposed to know this information had to be entered in forms?  And if I was missing a critical piece of information, why wouldn't the Error Check notify me and prompt me to add it?   The feedback I got from TurboTax told me I was good to go, even though it knew not all of the information had been provided.
