Total Tax Calculation Discrepancy

Need help reconciling a $1 total tax difference between me and TT, if for no other reason than it is driving me crazy.  Math seems straightforward.  $70,181 taxable income.  Married Filing Jointly.  10% bracket is $0 to $23,200, so $2,320 due.  12% bracket is $23,201 to $94,300, so remaining $46,981 ($70,181 - $23,200) is $5,637.72 due.  Total tax then should be $7,958--$2,320 + $5,638 ($5,637.72 rounded).  But, TT shows total tax as $7,957, $1 less.  What am I missing?  Does the IRS round down each tax bracket calculation versus following normal rounding rules?  Is this a TT error?  The numbers should be the numbers, so why the difference?  Appreciate anyone who can clarify.  Thank you.
