The code D indicates that you sold a nonqualified annuity. Such an annuity is not eligible for rollover. By putting the proceeds of the surrender of the nonqualified annuity into an IRA, you made a new IRA contribution, not a rollover. If the amount that you put into the IRA was more than you were eligible to contribute for 2021, you've made an excess contribution to the IRA.
If you told the IRA custodian that this was a rollover, you'll need to contact them to make the correction to show that this was not a rollover but was instead a regular contribution, otherwise the Form 5498 that they send to you and to the IRS will incorrectly show this as a rollover.
If this has resulted in an excess contribution for 2021, you'll also need to request that the custodian make an explicit return of excess contribution, otherwise the amount of the excess will be subject to a 6% excess contribution penalty every year it remains in the account.
