Get your taxes done using TurboTax

@baldietax is correct that Turbotax does not provide help for the AI method. Generally the AI method won't work if the bump in income is in the early periods because of the annualization.  one thing you might be able to do is increase your withholding for the rest of the year rather than pay estimates. by default, 1/4 of withholding is deemed paid each period regardless of when actually withheld.
