@KathrynG3 Thanks!
She is 19 and a full time student. She is filing separately, indicating that she is a dependent. As mentioned above, she had ~$16k in unearned unemployment benefits. The info posted above is from her doing her own taxes in TurboTax (with my assistance). TT automatically brings up the wizard for form 8615 under her tax return and we entered in the information accurately, but it still results in her having a much higher effective tax rate than it should.
