You are correct. The only items that actually change your return are the income adjustment and the withholding adjustment. Those other division pages are just informational as you mention.
Ideally, your income adjustment and your spouse's income adjustment should account for any changes that would occur when you make the income splits.
I suggest making a note of your adjusted gross income line 11 on your form 1040 before any splits. Then go back and actually input the income items as if you are splitting whether 50/50 or 25/75, whatever. Note the change in adjusted gross income. That will be what you put in the "Income Adjustment" box for form 8958.
Go back and put in the original numbers from your forms and enter the Income adjustment box number. Show the splits on the informational pages.
Whatever number you put in your adjustment box, you put an opposite change on your spouses return. Including the complementary splits on the information pages.
