Turbo tax assumed all withholdings were equal amounts. How do I input the exact dates

[swhite]

I put in exact dates, but review is showing an error message - that it must be the same each quarter

Follow these steps to select annualized method: (You must be using the annualized method of reporting income before you can use different amounts for tax payments.)

1. Go to Federal > Other Tax Situations.
2. Look for Underpayment Penalties.
3. Select Annualized Income Method.
4. TurboTax will ask you to break down your income and payments

Withholding is assumed to be equal throughout the year.  This is taxpayer friendly.  So even if a taxpayer was paid $50,000 during the year, but all federal withholding was paid in during the last month, the IRS will assume equal withholding during the year.  This is actually a strategy many taxpayers use to avoid underpayment penalties.  This really only works when the taxpayer has control over the business / payroll.

Why are you wanting to put in exact dates?

Are you being assessed a penalty?
