I need help with figuring out the 2021 tax for Line 16 on Form 1040. I provided the table my assignment gave me. By this table, their income tax should be $4741 but as you can see, my assignment says this is wrong. The taxpayers are Married Filing Jointly with a taxable income of $42,810. By this table, the amount lines up to be $4741. It says this is wrong. I cannot finish this assignment without this number.

I have also put in $4738, 4739, 4740, and 4742 and these were also ALL incorrect. Please do NOT provide me an answer with any of these numbers because the assignment says it is wrong.
