Common confusion points
What is my total income?

→ Verify that all relevant income lines have been included in line 9.

→ Ensure you correctly transfer any adjustments from Schedule 1 onto Form 1040-SR.

→ Confirm you have accounted for all credits by adding them in lines 19 and 20 before reaching line 24.
