The dependent was 19 at the end of 2022, and was not a student in 2022 or working. The capital gains were from mutual funds, and it was a net gain, no sales. I looked at the input for Child's income on the parent return- it said I needed to file a return for the dependent when I answered that an estimated payment had been made. the instructions said that an 8615 may be required.
If it's any help, the parent's taxable income was $54,797.
