Could you please explain further? You cannot refile without Netfiling a return. You need to NetFile first, and once you get a Notice of Assessment, then you can only amend or refile your return.

I used TurboTax to complete and Netfile my 2024 return in March 2025, and received my NOA.  In early February 2026 I received a revised 2024 T4.  I used TurboTax's REFile feature to enter this revised T4 to my 2024 return, when I attempted to Netfile through TurboTax, I found that Netfile was not available until February 23.  Now that it is after February 23, I would like to Netfile my the 2024 Refile that I prepared in TurboTax, but I cannot access this return in TurboTax, nor can I find a login for 2024 TurboTax.

Upon checking your profile, I do see you have used TurboTax Deluxe Online (DIY). Use this link to access Tax Year 2024: Tax Year 2024. Make sure to use the same credentials that you have used last year to retrieve your tax year 2024 return.
