How do I change "Spouse:" "Daytime phone" on the "Federal Information Worksheet"?

Go to the left side menu and choose Personal Information section and you can edit the phone number there.

The area of Personal Information for my wife does not have the Daytime Phone Number as an option to be edited?

Here is an FAQ: How do I update my TurboTax account info?

The Profile area does not have "my wife's" information. Therefore this solution does not work.

Did you follow step 2? That is not in the Profile area. 

Yes, I did... My Wife's information is Not part of my Intuit Account. Her name or anything else is not information that I see stored on that website/account.

Also, to be clear, I am not using online Turbotax. I have an installed copy on my PC.

Switch to Forms mode at the top.  Then open the Info Wks worksheet in the left column.  I think it's that one or maybe one by it.  I'll have to open my return and check the exact location.  

Yes, that Worked! The Forms Selection is Under View on the Top Menu.

Thank you for your help.

FYI - there should be a separate Forms button in the upper right (left on Mac).
