If taxable income is $93,198. According to my calculations tax liability should be $12,383. Turbotax is showing tax liability as $12,378. Is this calculation wrong?

If your taxable income is $93,198 and you are filing as Married Filing Jointly, the Form 1040 tax tables shown that the tax liability should be $12,378 - https://www.irs.gov/pub/irs-pdf/i1040gi.pdf#page=78

The answer is correct.  The calculation is correct.  If your taxable income is $93,198 as you wrote in your query, then the taxes on that amount if you are filing as Married Filing Jointly is $12,378.
Or are you saying the IRS tax tables are incorrect?

Thank you for the assistance. I was calculating using the IRS tax brackets and not the IRS tax tables.
