Thanks for the reply!
I have some followup questions.
- How can I make 1040es payment (for Q4 2022) now? All listed payment methods can only pay 1040es for the current quarter.
- I also owned a couple hundread bunks because I rollovered 401k (pre-tax to roth) in Q4 2022 and that makes my withold not enough. Is it possible to do quarterly forms and make 1040es payment to catch up and waive the underpayment penalty? I probably won't do that as it's toooo much work but I'm curious about the answer.
- I also noticed that TurboTax will change the underpayment penalty depending on the date of 1040es payment (I tried some dummy numbers). Say I managed to pay 1040es for Q4 2022 today (10/1/2023), it won't reduce any underpayment penalty. But if I claim I made 1040es payment for the same amount one year ago 10/01/2022, it can largely reduce the penalty. Is this expected (I always had the impression 1040es is for that specific Q and doesn't matter when the payment is made)?
