Computing Unused NOL to Carry Forward using Pub 536 Worksheet 2

I'm sturggling with Pub 536 Worksheet 2. Line 7 Adjustments to AGI. 

I'm good with Line 1

I created a second return in Turbotax omitting my NOL so I could compute Line 2 of the worksheet

Line 3 through Line 6 are zero

Line 7 is where I'm stuck

 

The instructions for Line 7 say to refigure my AGI using a list of 6 items of income and deductions. 

List Item 1 is Passive Real Estate Loss ($25,000)

List Item 2 is Taxeable Social Security $25,000

List Items 3 through 6 are not applicable to me

 

The instructions on how to compute the adjusted AGI don't make any sense to me. 

If it's helpful, this worksheet is for an NOL generated 3 years earlier that was carried forward year by year to this return.

 

I'll be grateful for any help you can give me to undestand the instructions.

Thanks!
