I have transferred my wife's disability amount via a schedule 2 but now I want to transfer my daughter's tuition. How do I open a second schedule 2?

Schedule 2 is Federal Amounts Transferred from your Spouse or Common-Law Partner. To accept a transfer of tuition from a dependant,  use the Dependant Information dialog box. If you have more than one dependant transferring tuition to you, then you can see a list of them on the Tuition Transfer Worksheet. 

If anyone reads this with the same problem I have discovered that the university transfer does not need a Schedule 2.
