Fafsa third question for parent income

Our 1040 was filed as married joint return.

The third question asks that I add lines 7, 12, and 18 for parent-1’s amount. My problem is that adding these numbers involves both parents. The fourth question asks the same, that I add 7, 12, and 18 which would yield the same amount. How do I answer these two questions for parent 1 and parent 2 without repeating the answer.

If you don’t have anything on line 12 and 18 (no business or farm income) then you can most likely use the federal wages number from each person’s W 2.
Make sure to put the right earned income with the right parent 1 or 2.
