@macuser_22 Yes those checkboxes are at the top of form 8615 and indicate the parent's filing status. My wife and I are filing joint. Our daughter is filing single. She's been filing her own tax returns for a couple of years, and indicates on her return that she is a dependent since we still claim her. She is an adult full time student under 24 years old.
I'm asking questions regarding daughter's tax return (which I'm helping her fill out), not mine and my wife' joint return. Daughter's income in 2020 was mostly from unemployment benefits, not interest and dividends, but it's all unearned and exceeds $2,200 (and exceeds $11,000 too), so form 8615 is required.
(My wife and I do not use TurboTax, so there shouldn't be any chance of our data getting mixed up with our daughter's. She inputs all of her information, except when TurboTax asks for her parent's information, which it does for form 8615.)
