There are no penalties for filing a tax return after the due date of the tax return if the tax return you are filing is for a tax refund.
A 2021 tax return with a tax refund can be filed at any time on or before October 15, 2025 with a 2021 extension.
Using TurboTax you can e-file a 2021 tax return at any time on or before October 17, 2022. After that date the 2021 tax return can only be printed and mailed using the TurboTax desktop editions, not the online editions.
You can download the 2021 tax data file to your computer and then open the data file with the 2021 desktop edition. If you have not paid for the 2021 online edition then you will have to purchase the 2021 desktop edition to compete and file the 2021 tax return
