Also, your calculations you provided above show the strict calculation by percentages for ordinary income. But be aware that the IRS Tax Tables do not follow the strict calculation you mentioned above. The Tables don't go exactly by the last 22% portion of your calculation. The IRS Tax Tables divide income into $50 increments. So everything within that final $50 level has the same amount of tax. For example, any taxable income amounts falling between $51,050 - $51,099 would all have a tax amount of $7,095 (for a single filer), according to the table, so this can vary a few dollars from the actual manual calculation using the 22% part.
Again, if the TurboTax tax calculation is less than the IRS Tax Tables, the most likely explanation would be the presence of qualified dividends or capital gains, if applicable, calculated on the Qualified Dividends and Capital Gains Tax worksheet.
