Tax Computation 2024 incorrect

when I filed my 2024 taxes in april 2025, turbotax calculated the tax amount on line 16 of the 1040 about 400 less than it should be relative to the irs tax tables.  When I used it today, the amount was correct.  Was there a known problem?  Is there another reason why the calculated value in line 16 does not match the tax tables?
