WA has no state tax but WA actually has a couple of credits that can be claimed this year by filing. The program will hold information it deems important. Since you have the desktop version, you can take a look at the WA form and see if you qualify for credits.
As for CA, you can contact support and tell them you wanted the CA not WA. We don't handle financial issues here in the community, just answer tax questions.
If you do need to mail in your return, be sure to sign and date then mail with tracking, no signature required.
