I was filing 2023 taxes. Quebec successfully submitted. then my account timed out before submitting federal taxes.

Logged back into my account. Even though I have a confirmation that Quebec taxes submitted, Turbotax is prompting me to resubmit Quebec instead of letting me pick up where I left off and let  me file my 2023 federal taxes.
 

Filing

You can select File> CRA Online mail from the right side menu to go back to the start of the filing section.  Or if you see Tax Home in your right side menu. you can click on that and then Finish & File.
