If issue is caused by IT-201/203 Line 16 having an ELA adjustment with CARES Act provisions applied, the return is rejected due to a program defect (ATC-278562). The fix will be addressed in a future release. 

This adjustment doesn’t fit the current NY schema framework and Business Rule. Once we release a program update, return can be paper filed. Unfortunately there's no workaround on this. We apologize for the inconvenience.
