Why cannot I transmit my return with today's date?

Be sure you are using 2019 for the year and not 2018.

If you select the Transmit Returns Now button, and it doesn't seem to be working, the most likely source of the problem is “cookies,” little pieces of code that are sent to your browser so we can personalize your experience.

Please see the TurboTax FAQ below for more information on resolving the issue:
