Reporting excess Roth contribution earnings

I removed excess Roth contributions prior to filing my extension this year. I will not get the 1099R from Vanguard until 2025. Can I just wait and file an amended return next year or is there a way to declare this on my 2023 taxes? Someone mentioned creating a dummy 1099-R, but I am a little nervous about the information not matching next year's 1099. Thanks!
