To clarify a bit further:
Your situation is covered in IRS Publication 946 at https://www.irs.gov/pub/irs-pdf/p946.pdf starting at the bottom of page 13 and continuing to page 14.
You cannot amend prior year's returns to fix this, because you have not depreciated the property for "2 or more consecutive years". As @SharonD007 stated, you'll have to include IRS Form 3115 - Change in Accounting Method, with your tax return. You have two choices. You can wait until your e-filed and accepted 2022 tax return is processed in it's entirety and then amend it to include the 3115. Or you can just wait until next year and include the 3115 with your 2023 tax return.
Now while the TurboTax program does include the 3115, it is not simple by an stretch. I would highly recommend you seek professional help to fix this. Doing it wrong can (and will) make things worse. If your state taxes personal income, that could be a double-whammy. The potential fines, penalties and back taxes from doing things wrong can make the cost of professional help seem like a pittance in comparison. So please seek professional help for this.
When/if you seek professional help, ensure you get a printout of the return from the preparer that includes all worksheets and calculation forms, as you will need it if you wish to continue using TurboTax in the future.
