A 2019 return cannot be prepared online. It has to be prepared using 2019 desktop software (see link below.) And it cannot be efiled. It has to be printed, signed, dated, and mailed. It's recommended to mail by a method that has tracking such as certified mail, priority mail, etc. If you have both Federal and state returns be sure you mail each one to the correct tax agency.
Here is the link to the 2019 software to purchase as a download directly from TurboTax:
