I have already filed my taxes this year with turbotax and realize that I made a mistake checking a box for my tax profile, so what should I do to correct this?

You have to wait until you get a Notice of Assessment from CRA and you can Refile with correct information after. If you have used TurboTax Online version, you will a 'Refile button' in front of the Tax return. If you used the download version you can click on ' Change a filed return'

NOTE: For other ways to change/edit your filed return, please see our TurboTax article: How to Change Your Tax Return After You’ve File

Thanks for choosing TurboTax.
