Thanks RalphH1 for your answer. A TT expert told me that I could use the "send check option" for the amount due on the unreported income but not send the check for the additional amount and explain in the comments that I just want to reduce the amount of my application to estimated tax. But if I can't change the amount that my original return said to apply to estimated tax, then perhaps I need to pay the difference after all? The problem is, on the REVISED 1040, while it says zero tax due, the amount to be applied to estimated taxes has now been reduced by the amount the amendment says I owe. So the revised 1040 uses the lower amount as "amount of line 34 you want applied to your 2023 estimated tax .." yet by paying the additional, I should have the FULL original amount applied to my 2023 estimated tax. which would not be showing on my amended return. What will happen to the additional amount I pay that I really don't owe? Can I add it to the newly reduced estimated tax amount as to reach the original total of estimated tax paid when I file next year? or will they refund it to me because they will correct the amount applied to estimated tax to the amount that is on the new corrected 1040?
