Hi! we are currently working on i864 and Im confused if we should use line 22 of 1040 as income (for self employed) or line 37 of adjusted gross income or line 7, part 1, schedule c of form 1040?

coz our co-sponsor is self employed and he filed his income tax jointly with his wife. should we also include i864a?

Thanks

Use line 22, total income, of the 1040. Net profit, line 31 from the Schedule C, is listed on line 12 of the 1040 as business income.
