When you reported the 1099R for 2020 did you elect to spread the tax over 3 years?  Here is a prior answer from Don......

If you had a Covid-19 related distribution in 2020 and selected to spread the distribution over 3 years -

Answer No when asked if you received a Form 1099-R in 2021, if you did not receive the form

Answer Yes when asked if you took a disaster distribution

Answer Yes when asked if you took a Qualified 2020 Disaster Distribution

Check the box that this was a Coronavirus-related distribution reported in 2020

If the 2020 distribution was from an account that was Not an IRA

2020 Form 8915E Line 9 - Enter 1/3 of the amount from the 2020 distribution in both boxes for Line 9

If the 2020 distribution was from an IRA account

2020 Form 8915E Line 17 -  Enter 1/3 of the amount from the 2020 distribution in both boxes for Line 17

The 1/3 of the amount from the 2020 distribution will be entered on the 2021 Form 1040 Line 4b if from an IRA or on Line 5b if from a retirement plan other than an IRA

Or do you actually take a plan loan, rather than distribution?  If so, no 1099-R issued for that unless you default on repayment..

You did not do anything in 2021 and that's why there is not any 1099-R for 2021.
