I agree with RalphH1 that you could file now by entering what you expect to be on the corrected Form 1099-SA. However, you also have the option to submit a request for extension and file after you get the corrected form. Any expected tax liability still needs to be paid by April 18, 2023 even though you would have until October 16, 2023 to actually file your tax return, but, if you are due a refund, filing later on extension would likely mean getting the refund later than you would otherwise get it.
