P.S. in the article above it refers to how to handle 8606 from prior year if not filed for a prior basis, not sure your situation but may not need to refile 2023 if there is no tax impact once it's sorted out. Form 8606 instructions may have further guidance on how to handle updates to unfiled or previously filed 8606. Outside my wheelhouse just wanted to draw your attention to that section in the help article.
