Deductions & credits

Sorry I am still confused. I followed step 1.

 

The amount of Loss from Schedule D (540), line 11, stated as a positive number.

 

My tax form says 305 for line 11. Is that all I need to do to enter my CA loss carryover from 2022 or do I need to do any other calculations after step 1? What is step 4 and 5 calculations for?
