Solved: After a couple hours of frustration trying to fix my return to file an amendment, I found a small worksheet (out of the roughly 100 worksheets in my return) that showed why there was $0 under 2024 Fed Liability.
In Oregon, the federal Premium Tax Credit is taxed as income and reduces the Federal Tax paid deduction. In my case , it brought it to zero.
I'm actually relieved to know that TurboTax wasn't the cause.
