T2 Adjustment -Sch550 co-op tax credit

After I filed a T2 return, I found out about a Co-op tax credit which could have been applied. When I did an adjustment to the return, everything looks OK, but there is no T2-Adj form that gets created to file this change. Has anyone else experienced this? What is the best course of action?

Thanks.

T2 adjustment does not work like T1 adjustment, similar but not the same.
To adjust T2 return, simply answer yes to the adjustment question in Info and in T2ADJ form, provide a reason for the adjustment then retransmit. The entire T2 return will be refiled.
