I am using Turbotax Premier 2021 to file my tax return. I am married filing jointly. After entering all the information, line 15 Taxable Income on Form 1040 is $168339. line 16 Tax is $28495. But according to the tax calculate worksheet from IRS, tax should be 168339x0.22-8503=$28531. There is a $36 difference. Please advise what is the problem with the calculation. Thanks.
