Foreign tax credit - Form 1116

I have reported foreign income in the income section of Turbo Tax premier. I have also paid foreign taxes. I have an $800 taxes due, and $3K in foreign tax available credit. The tax credit doesnt seem to get applied to the taxes due. The foreign income was primarily interest, dividends and capital gains due to sale of stock, and was reported as ordinary income on 1099-SR. The $800 tax due is because of Affordable Care Act subsidies.

 

Any ideas why the foreign credit doesnt get applied.
