Virginia Credit for Tax Paid to Other States

I was a part-year resident of both CA and VA, but continued paying tax in CA after I'd moved to VA.  Does this need to be entered under VA Credits & Taxes: Credit for Tax Paid to Other States?

 

Or perhaps I'm just getting a software error.  When I go back to the VA Credits & Taxes section and click on "Credit for Tax Paid to Other States", I am returned to the same navigation page.  I do not go anywhere.  The "Revisit" button seems inactive?!

 

Thanks!
