@sandy4042 I have been known to do what ifs after filing to check what might happen next year and I use the old year to update and print the Form 1040-ES for each quarters estimated taxes. I keep the original filed forms and the for record forms (with worksheets) in pdf files. I save and rename the file that I am changing after filing so at least the original data is there in the original file. That will not prevent TT from recalculation after updates through the year, but at least I have the pdfs as a record of what went to the IRS.
