I entered it as a 1099-NEC income. I don't think TurboTax has asked me a date or dates of when this gig job was performed. My understanding of Estimated Payments is that based on current year's income, you should estimate next year's estimated tax. This particular 1099 job was a one time job that I performed and was not estimated in 2022. You are right, TurboTax has calculated across all 4 quarters and that's why IRS corrected it and sent me a refund of penalty.
