While in the return, and only once the return has been completed, find the Diagnostics button and click it to check the return for any issues. If there are any diagnostic errors present, they will be shown in red and will be clickable. Clicking these errors will take you to the issue in most cases.
If there are no errors, you may then click on the Create E-File button along the bottom of the Diagnostics window. After a short period of time, you will receive a notification in the top-left corner informing you that your E-File is Created.
Afterwards, click on the Send E-Files tab and you will find your created e-files listed here and ready for sending.
