After doing some more reading I agree with TaxGuyBill.

Appears you would need to amend returns and eventually use Form 3115 when sold.
Below is from this link: https://www.msatp.org/fixing-the-error-how-do-we-solve-depreciation-mistakes/

Amending returns will only correct depreciation errors that have occurred in the last three years. Errors that have occurred before that cannot be “caught up” on current or amended returns and will only be “caught up” when the asset is sold using a Form 3115 and Code 107 as discussed below.
