If you are using TurboTax Online, to enter the estimated tax payment you made:
- In the Federal > Deductions & Credits portion of your return, scroll down to Estimated Tax Payments.
- Click Start/Revisit next to Federal estimated taxes for 2021.
- Click Yes.
- Enter your fourth-quarter payment amount and date.
If you are subject to an underpayment penalty, you may want to visit the Underpayment penalty section at Federal > Other Tax Situations > Additional Tax Payments. If you allocate a majority of your income to the 4th quarter due to the Roth conversion, this could reduce or eliminate the penalty.
