This is what I understand are the facts in your case.

You received a 2023 1099R coded that the transaction is taxable in 2022.  This amount needs to go on the 2022 return which you already filed.  The brokerage firm gave you a mock up form last year showing what the amount would be, and you included those amounts on the 2022 return.  But those amounts were wrong.  Now that you received the real form, it is different from what they projected by $24.84 of taxable income.  The IRS only got the 2023 1099R that you just received and will see it is different from what you reported by $24.84. 

In this case, for such a small amount I would just wait for IRS to respond instead of amending a return.
