@moss11 2019 can still be filed by mail. it can not be e-filed. if it's complete you'll need to print it out and mail it following the TurboTax filing instructions. there is probably a fee.
if it's incomplete you would need to purchase the desktop software to complete it. you can upload the .tax2019 file to complete the return rather than having to start over. make sure all updates are installed before filing
