If you are using TurboTax Online and you haven’t
submitted your return via NETFILE, then you can still make changes to your
return. You will not be asked to pay again if you already paid or put in the payment
code for the return. But you still will be charged if you upgrade the return or
add features, you’ll just have to pay the difference. Also, if you make a copy
of the return, the copy will count as a new return, so you will be asked to pay
to file or print the copy.
