Overpaid taxes 40% for cashing out 401k. Turbo says we only should have paid 10% or 25% Which is it?

[BobinCT]

The TurboTax "10 or 25%" thing is with reference to the WITHHOLDING that would be taken, NOT the ultimate tax.

[MinhT]

When you withdraw from your 401(k) before the age of 59 1/2, the amount withdrawn is subject both income tax and the early withdrawal penalty.

The early withdrawal penalty is 10% of the amount withdrawn. Income tax on the the amount withdrawn depends on your tax bracket. If you are at the 28% tax bracket then you pay 28% in tax, making it a total of 38%.
