Thx a lot, very helpful! Just one last clarification: when I entered the Forms mode, the specific line I want to edit did not allow me to select override, not sure why. I could however manually edit the number to the new correct value. After my manual edit, I confirmed that my correction also adjusted the subsequent numbers in the rest of the form. I then when back to the "interview mode" and was able to complete all checks without errors. Does this mean my manual edit is not fully adopted, and i can efile?
Please advise. Thx in advance.
