community property adjustment

Every year, I manually divide community property between my spouse and I as I fill in the forms and show the division on IRS form 8958. This year turbotax has a new section where it asks me for community property adjustments after I have already added all the manually divided information. Two questions:

1) what calculations/changes does turbotax do with this information?

2) Can I just skip this and fill out the 8958 manually?
