My spouse and I have a mix of community and separate income. For the community adjustment, what number am I adding to/subtracting from? AGI? Only community income?

When I am filling in "Community Property Addition Adjustment" and "Community Property Subtraction Adjustment" what's the baseline I'm using for the adjustment? My total income ("separate" + "community")? Just the portion of my personal income that's being treated as "community income" (and not including the portion of my personal income that's "separate income")?
