After you file

No you cannot start preparing your 2022 tax return here yet.   The software for a 2022 return will not become available until sometime in November.   You do not say what software was used to prepare your 2021 return.   When TurboTax for 2022 becomes available you may be able to transfer your 2021 tax file in the 2022 return, depending on what software you used, and whether you have the tax file.  If you only have a pdf of the 2021 return then very little data transfers from a pdf.
