Form 2210AI tax calculation?

[krr28]

I need help understanding how TurboTax is calculating the tax on line 14 of schedule 2210AI 2025. I can get the number produced by TurboTax for columns b through d, but the tax value calculated by TurboTax for column a is half the value that I calculate. The line 13 taxable income is $114,816. The total qualified dividends and capital gains are 4*(17,726+265). I calculate a tax of $15459 but TurboTax calculates a tax of $7385. Is there anything special going on with the first pay period? Please help me understand the difference.

I was able to calculate the same amount of tax calculated by TurboTax.   I failed to calculate the amount of the capital gains that is taxed at 0% because the taxable income minus the capital gains is less than $96700.  This is now solved.
