Get your taxes done using TurboTax

@jimr63 You can e-file your federal tax return without e-filing the state return at the same time.  You can change to file by mail for the state return and after the federal return has been e-filed and accepted by the IRS you can go back and change the state return to e-file from mailing.

Go to the File section of the program and on Step 3 click on Revisit.  Then change how you want to file the tax returns.  See these screenshots (even though the screenshots are for 2019 the procedure is the same for 2021)
