I ended up owing for 24'. TurboTax put estimated 25' prepayments for my state tax on my return, but not for federal. Does that mean they don't recommend it?

TurboTax automatically generates the estimated tax vouchers based on details of your current tax return. If they weren't generated, it's because you don't need them.
