What happens often when preparing spousal returns together, is only one of the returns actually gets NetFiled.
If you prepared your returns together and only one was successfully NetFiled, you'll need to go back into the tax return, start at the Review section, address any Warnings and Errors, then continue through to file your spouse's tax return.
You should receive a separate NetFile Confirmation Number for this tax return. Take note that CRA will not be accepting any NetFile transmissions as of 11:00 pm EST on January 22nd, 2021.
The annual closure to convert the CRA systems for the 2020 tax filing season will reopen on February 22, 2021.
