Sorry to bring up an old post, but it fits my situation exactly as well. I am preparing my 2024 return and am seeing this for the first time; I've used TurboTax for many years prior. I have regular twice-per-month income and my tax payments are taken out of each check. There has been no substantial changes to financials this year, and as a single filer I typically have to pay some to both federal and state (MI). There is nothing new in my situation for 2024, so why would I see this same scenario (TT saying that I have to pay a penalty for underpayment of estimated taxes). I don't make estimated tax payments and never have; my employer takes it out of my check 24 times per year. I'm pretty sure I'm having the highest rate taken out (single), short of making additional dollar amount payments from each check in addition. Did I check a wrong box somewhere prior in the TT interview?
