Are you trying to fill out the FAFSA? If you filed your 2019 tax return with TurboTax Free Edition you would not have Schedule 1 or Schedule K-1. So all you need is the amount on your Form 1040 line 1.
(Schedule 1 line 3 is business income or self-employment income. Line 6 is farm income. The Box 14 that the FAFSA refers to is on Schedule K-1 from a partnership.)
See the instructions that VolvoGirl gave you to get a copy of your tax return if you do not already have a copy.
