I am a CA resident and also filed a nonresident NY return. It's showing NY return has been e-filed. I cannot find a copy of my NY return in my account.

If the complete tax return is not showing up in the PDF download on the Tax Home website, use procedure instead -

When you sign this onto your online account and land on the Tax Home web page, scroll down and click on Add a state.  This will take you back to the 2018 online tax return.

Click on Tax Tools on the left side of the online program screen.  Then click on Print Center.  Then click on Print, save or preview this year's return.  It is wise to save the return PDFs  two ways  for your records  ... once  as filed and again with all the worksheets included.
