It would be best to transfer from the actual tax file. But I don't know if you can on Mac.
You can transfer TaxAct and H&R Block pdf to the Mac Desktop CD/Download program
Can I transfer last year's PDF to 2021 TurboTax for Mac?
But be aware transferring from a pdf only transfers basics info like name, address, ssn and AGI. So you might as well enter everything from scratch. The FAQ says...
- From a PDF—which will transfer your personal info and your AGI to give you a head start.
