Where do I find my total federal adjustments to income?

[Texas Roger]

The total is shown on line 8a of form 1040 or on Schedule 1 line 22.

[DoninGA]

On your Federal tax return Schedule 1 will have adjustments to income.  The total from Schedule 1 Line 22 flows to the Form 1040 Line 8a.  Your adjusted gross income is on the Form 1040 Line 8b.
