In version 10.2.43455.0 (released May 31, 2021), the Create T4, Create T5 and Create T5018 buttons are missing from the Data menu of the latest module of TaxCycle T2.
Until we add the buttons to the latest T2 module, you cannot create a T4, T5 or T5018 file from a T2 return. The buttons still appear in the prior T2 modules.
This issue was resolved in the latest TaxCycle update.
