Thanks for your response! I double-checked and the due dates were all met, paying $1353 each for Q1, Q2, Q3, and $1352 for Q4, totaling $5411 and the same as my 2023 Federal total tax. I'm baffled... Does TurboTax perform a final check that might flag this as an error and remove it before filing? Or is there a way to query live help without upgrading since I have no other problems or questions? TIA!
