if you filed using TT software on your desktop/laptop, open the 2020 tax file in TT then click on print center button on top right. select 'specific form' option from the drop down window that opens. If you filed online, I'm not sure as I've not done that but if you were provided a PDF file for your records, you should be able open that file and scroll to form 1040 and print that page(s). Otherwise, you'll need to ask someone that files online..
