@jmaitland3 You should create an entirely new account for 2024 (new UserID, new Passwd). It's very difficult to remove the person who was listed first on a prior year's account.
Before you exit your 2023 account, download the PDF from all years that are available in that account (if you don't already have them), and store them in folders at home. ..TTX deletes anything older than 7yrs back, as each year changes..annnd You may need your 2023 tax papers for reference of some things to prepare 2024 taxes.
