When you requested the extension you were supposed to pay your estimated tax due by April 15, 2025. The extension did not give you extra time to pay--it only gave you extra time to prepare your Form 1040. Did you somehow click that you had also paid? You will have to correct that and pay when you file----expect a bill from the IRS because you will be subject to interest owed. TurboTax will not calculate the interest you owe for paying late.
Go to Federal>Deductions and Credits>Estimates and Other Taxes Paid>Other Income Taxes
If you did not make a payment when you requested your extension then make sure that you edit whatever it shows for that "payment".
@nathan-r-moser Oh---Now I see that you already e-filed the return with an incorrect payment amount on it. The IRS will figure out that you did not actually pay. Pay them asap by mailing a check or money order with the 1040V or by going on the IRS payment site.
