Can a Nonqualified HSA Distribution from January 1 - April 15 Apply to Prior Year?

Basically - I overcontributed to my HSA in 2023 and no longer have a HDHP. I paid the 6% excise tax for 2023.

I am now trying to remove the overcontribution for future tax filings. If I withdraw the overcontribution + gains today (February 2025), can it be applied to 2024 taxes even though a 1099-SA will not be generated by the custodian for this distribution prior to April 15? All guidance I can find on the topic only points to being able to contribute until April 15 (not the case here) and withdraw the excess contribution up to April 15 of the same tax year (also not the case here).
