Can I electronically file my 2018 tax return today if I have earned income?

No - you cannot e-file a 2018 return, only a current year 2019.. You will need to send it by mail.

To complete and file a 2018 tax return using TurboTax you would need to purchase, download and install on a personal computer one of the 2018 desktop editions from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/

A 2018 tax return can only be printed and mailed, it cannot be e-filed.
