I missed a form on my 2023 taxes, it came late. The FAQ says there is a refile button that should be beside my old returns - none of them have a refile option.

Did you print to mail your tax return or electronically Netfile it?

Thanks for choosing TurboTax.

I netfiled it.

I just fixed it on the CRA site.  Much easier than trying to figure it out through TurboTax.
