Deductions & credits

I have an HSA in 2019, but TurboTax says it is all taxable because I WAS claimed as a dependent on my parent’s return. However I WASN’T claimed. I could have been claimed by them. I answered the applicable questions correctly in Gen Info. Other tax software (Taxslayer and IRS Free File) got it correct. How can I get TurboTax to do it right?
