I filed with Turbo Tax. I started to amend my 2022 but never filed as I am having a CPA amend my return for 2022. How do I get the original return I filed?

You were supposed to save the original as a pdf before you began to amend.  If you did not do that, then the amended return overwrote the original return.  You can seek a copy of the return from the IRS.

you can get a free transcript from the IRS or for a fee of $43, an actual copy of your tax return.
