turbotax calculates 2020 estimated taxes wrong?
For a given projected 2020 taxable income, TT shows a projected income tax that is significantly different from what you get in IRS's 2020 Tax Rate Schedule, as shown on "Estimated Taxes and Form W-4 Worksheet". (e.g., for a taxable income of $62,583, it calculates $2,578 vs I calculate value from schedule of $7,114, for married filing jointly). Seems wrong.
(Note: If I say I only have WAGE income, then tax is calculated correctly. Problem occurs once you add Sched C income.)
