I need a copy of my 2020 tax refund

@Sarapartida I believe you mean how can you obtain a copy of your 2020 tax return.

If you prepared your tax return online with TurboTax, you can download previous year tax returns and then print them using your computer. To do this, log into your TurboTax program, by entering your user name and password, then you will see an option on your Tax Home page for Your tax returns & documents, where you will see the tax returns from previous years that are available to be downloaded.
