The day I filed my tax return with turbo tax, the website told me to print a PDF, but the site failed, where is that PDF that I had top print and mail with my check to CA

Have you paid the TT fees?

Please see this FAQ how to get a copy of your return:

Another option to print that includes the worksheets:

Please log back in your TurboTax account and "add a state" to open the return back up (you are not really adding a state, just to open it back up), then select Tools on the left, Print Center and choose the print center, then select returns and choose to print just the tax return or to include all worksheets as well.
