Unfortunately, there is no way to downgrade a TurboTax product once it has been upgraded. If you are using TurboTax Online, you’ll need to start a new return to change your product. To start a new return, select “Start a New Return” from under “My Returns” in the top left corner. Once you have started your new return, you can select “View All Returns” from under “My Accounts & Returns”. Then delete the unwanted return by clicking the small Trash Can next to it or “Delete” under the return’s name.
Thank you for choosing TurboTax.
I don't have anything in box 46 or 85 of a T4. I only have a T4A from a co-op and RRSP withdrawals on a T4RSP. No self employed income or rental income. There are medical or other deductions. I have not yet upgraded from the free version but it won't let me file unless I do upgrade
If you entered medical expenses you will need to upgrade to File your return.
Thank you for choosing TurboTax.
