You will not get another form 1099-R this year.
You will report the second taxable portion of your 2020 coronavirus distribution in the Retirement section under Wages and Income of TurboTax.
However, this section is not yet ready as the IRS has not yet issued instructions for form 8915-F and you'll need to revisit this section later.
Please read this TurboTax Help topic on form 8915-F.
