Are you in the correct section? The state estimated tax payment section in Deductions & Credits includes a Fourth Quarter box with a January 15 date.
To enter your quarterly state tax payments in TurboTax:
Enter your quarterly payments. If you paid on different dates you can change them.
You must make estimated income tax payments if:
1. Your Connecticut income tax, after taking into account your Connecticut tax withheld, and any Pass-Through Entity Tax Credit (PE Tax Credit) you are allowed to claim, is $1,000 or more; and
2. You expect your Connecticut income tax withheld (including any PE Tax Credit) to be less than your required annual payment for the 2020 taxable year.
Your required annual payment is the lesser of:
• 90% of the income tax shown on your 2020 Connecticut income tax return; or
• 100% of the income tax shown on your 2019 Connecticut income tax return if you filed a 2019 Connecticut income tax return that covered a 12‑month period.
