Are you wanting to file a tax return for someone else or for your self?
If for yourself, you cannot file another 2023 tax return if you have already filed the 2023 return. To make any changes to the 2023 tax return you filed you must file an amended return.
If the return is accepted you will have to amend your original tax return. An amended return, Form 1040-X, can only be printed and mailed to the IRS if the original tax return was not e-filed. The IRS will take up to 20 weeks or longer to process an amended tax return.
Before starting to amend the tax return, wait for the tax refund to be received or the taxes due to be paid and processed by the IRS.
See this TurboTax support FAQ for amending a tax return - https://ttlc.intuit.com/turbotax-support/en-us/help-article/tax-return/amend-change-correct-return-a...
If for someone else, you will have to create a new account with a new User ID. The TurboTax online editions can only be used for one tax return per account and User ID.
