I need to file Form 2210 and check Part 2 C, but TT is not allowing me. This is making my Taxes much higher. How should I correct this?

To annualize your income for Form 2210 in TurboTax Online:

1. In the search bar, type "underpayment of taxes" and select the "Jump to" link.
2. On the Underpayment Penalty Screen select "Yes" to whether you want to review your underpayment penalty.
3. When asked if you want to use the "Annualized Income Method", select Yes.
4. Enter your Adjusted Gross Income (AGI) and withholding for each period/quarter.
5. Continue through the interview and Form 2210 will be file with Box C checked in Part 2.
