Part 6. Sponsor's Employment and Income
My total income(...)as reported on my federal tax returns on the most recent 3 years.


For couple filing joint returns, the Total Income on the tax return is the sum of both spouses income less applicable deduction.  Do I suppose to report this Total Income as listed on the 1040 form,   or do I need to break it down to reflect individual income without the consideration of deductions.

Appreciate your clarification.
