When I look up the income from 1040 line 15, calculated by turbo tax, with 2020 Tax Table line 16 don't agree. Turbo Tax, line 15 shows $11,156 and the table lookup would be $11,562 for a difference of $406 in my favor. For my mother in-law Turbo tax, line 16 shows $0, the table lookup based off Turbo Tax line 15 the table look up would be $533. Why are they different?
