Does only child, full time student w/unearned income & dependent on my return need to complete form 8615 titled Other Children Completing Form 8615?

Form 8615 must be filed for any child who meets all of the following conditions. 

1. The child had more than $2,100 of unearned income. 
2.  The child is required to file a tax return. 
3. The child either: 

•  Was under age 18 at the end of 2017, 
• Was age 18 at the end of 2017 and didn’t have earned income that was more than half of the child's support, or 
• Was a full-time student at least age 19 and under age 24 at the end of 2017 and didn’t have earned income that was more than half of the child's support. (

If the above apply then you will need to enter the amount of the unearned income.  

If these do not apply, you will need to click on TaxTools>>>Delete a Form>>>click Delete next to 8615

If that does not clear the issue go back through your interview questions and re-answer the questions on your child and then also click Federal>>>Income and Expenses>>>Scroll down click Show More next to Less Common Income>>>Start next to Child's Income (Under age 24)
