E-filing for the 2019 tax filing season closed permanently and forever on Oct 31, 2020. You have no choice but to select the "Print and File" option. When you print an instruction sheet will be printed with it. The instruction sheet has the address you mail it to, along with information about any other documents you will need to include with your mailed federal return.
If you also need to file a state return, then a physically separate instruction sheet will be printed for the state return. You do not under any circumstances mail your federal return and your state return to the same address. There are no exceptions.
