Are you using TurboTax CD/Download or TurboTax Online?

I downloaded the program, not from CD

You can go into Forms mode, then select the PRWS form on your return. Click Edit from the top grey menu, then Forms > Clear Current Form.

I think this is a program bug. I have the same problem.

To fix this, you can go into Forms mode, then select the PRWS form on your return. Click Edit from the top grey menu, then Forms > Clear Current Form.

I have the same problem.  The generic message I'm getting is "One or more entries in your return require correction.  The data entered is either invalid or mandatory information is missing."  When I print the CRA version of my spouses return, I'm getting the "Principle Residence Designation Worksheet".  Certainly a bug.

@Phil6226 You can go into Forms mode, then select the PRWS form on your return. Click Edit from the top grey menu, then Forms > Clear Current Form.

This step doesn't work.  The form is blank, but is still there.

You can remove the form as seen in the image below.

Thank you for choosing TurboTax.
