Can I use turbotax to file a T1 adjustment?

[Lou8]

This is for a prior year return, not current year. Or does it have to be done manually? thank you.

If you NETFILED your return using TurboTax, then you can use ReFile to adjust the return.

This TurboTax FAQ tells you how to use ReFile: I've filed my tax return. Can I still make changes?
