Retirement tax questions

When did you actually get the interest?  They must have paid both to you in 2021.  Now wait a minute.  For what tax years?  How did you record 2020 interest in 2020?  You wouldn't get your 2020 refund until you filed in 2021.   And we are just filing 2021 now.  Does the 1099 have 2 amounts for 2 years?
