The only way to "mark zero for line 1 of M1M " is to override it. Line 1 of form M1M is automatically calculated -- it is grabbing the in the values from line 2a of my 1040 and also adding the values from line 1 of my schedule KF. (Again, both of these documents report the same fact.)
The only way to change it without an override is to alter my Schedule KF.
But isn't there going to be a problem that my reported Schedule KF doesn't match the one prepared by the fiduciary?
