If you used the "Online" software for your 2019 taxes........just don't use the same "Online" tax account that you filed your 2019 taxes from...only use a new account.
..................(or better yet...use desktop software every year, that allows you to have different test files , and even a special "What-If" worksheet in the current tax return that allows you t see what would happen the next year, but without destroying your current tax file)
