If you override Sch C then it may cause issues with e-filing. 

You mentioned "without transferring data". Is that year to year transfer or Fed to state transfer? Fed to state transfer cannot be removed but year to year transfer can be removed with removing the state return. 

May I ask why Sch C does not work for you? Column C is the AL adjusted amount. In your case, it is a resident trust so Column C reports all source Fed amount adjusted for AL purpose (like conformity, tax deduction adjustment, etc.). Please provide more details so I can help you with troubleshooting.
