My daughter selected "someone can claim you as a dependent" on her 2018 return as she was a college student and assumed we could claim her. Her AGI was $21,895 and she did take the Standard Dedcution of $12,000 on line 8. We were told we would receive no benefit from claiming her as a dependent on our return as our combined AGI was $252,000 and that she should amend her return. As I look at the Instructions for Form 1040X on page 9 in the table changing exemption information is "NA". Maybe I do not understand the difference between a dependent and an exemption but does she need to file an amendment? Is there any value in doing so? Where on the 1040X form would we make that adjustment? Thank you!
