You cannot combine tax years and put 2022 and 2023 together.
Each tax year has to be filed separately using the forms for the specific tax year. They cannot be combined in any way--do not even put them in the same envelope when you mail them. Software for past years is available back to 2019. Any earlier years can only be prepared on paper forms by hand--and those refunds have been forfeited now.
There are no second extensions. So.....after the October 2023 deadline you will just be late. Online tax preparation and e-filing will close after the October deadline, so if you miss it you will need to use the CD/download on a full PC or Mac, and mail your 2022 tax returns.
If you are getting a refund, there is not a penalty for filing past the deadline. If you owe taxes, the interest/penalties will be calculated by the IRS based on how much you owe and when they receive your return and payment. The IRS will bill you for this; it will not be calculated by TurboTax.
