If you have a prior year tax return available, the only way to compare using TurboTax would be for you to purchase and download one of the TurboTax prior year desktop editions (2021 thru 2023) to install on a personal computer, Windows or Mac. Then complete the tax return using TurboTax so that you can compare to what you have on hand.
