My spouse's CRA account shows that he hasn't filed his income tax for the year 2019 although we filed a shared one through your platform?

When you complete a joint return;

• If you’ve prepared a return for your spouse/partner together with yours, your returns must be filed one at a time. You’ll need to select the NETFILE CRA button for each of your returns. TurboTax will bring you back to this step to file the second return once the first return has been filed.
• On the NETFILE your Return to the CRA step, select Agree and NETFILE. TurboTax then transmits your return to the CRA for you.
• On the pop-up Congratulations! step, select Continue.
• A NETFILE confirmation number appears on The CRA received your NETFILE return step to confirm your return has been successfully received by the CRA.

Please go back and open your return in the bottom left click on FILE- and continue to file and click on NetFIle beside your spouse's name.
