As RobertB4444 indicated, in this case you would to omit reporting the $8,000 IRA contribution. Because it wasn't an excess contribution, if you entered the contribution TurboTax would not give you any opportunity to indicate the amount of contribution returned. TurboTax only presents that opportunity when TurboTax determines that you have entered an actual excess contribution.
You must still enter the code-8 2024 Form 1099-R so that the $266 will be properly taxed.
