There are two things you might be missing.
1. If you received more than $10,200 of unemployment benefits, your tax will increase when you enter your unemployment because only the first $10,200 is not taxed. You have to pay tax on any unemployment benefits over $10,200.
2. If your Adjusted Gross Income (AGI), not including unemployment, is $150,000 or more, you are not eligible for the exclusion. In that case, all of your unemployment is taxable.
In any case, do not file an amended return. If you are eligible for the exclusion, the IRS will recalculate your tax return and send you an additional refund. It might be a couple of months before you get it. It doesn't matter what TurboTax does or does not do. The IRS will do the recalculation, not TurboTax.
