Question about two different EFC for 2 students

What is the student’s AGI from the 2019 IRS 1040, line 8b? This should be reported on FAFSA line 36. How much of this AGI is from taxable scholarships? This should be reported on FAFSA line 43d. Are you getting the error message when you attempt to make the FAFSA line 43d entry, even though the line 43d entry is less than or equal to the 2019 AGI entered on FAFSA line 36?
