The IRS allows an HSA owner to “correct” the mistake by returning the distributed amount to the HSA and treating it as though the distribution never occurred. An HSA owner has until April 15 following the first year the HSA owner knew (or should have known) that the distribution was a mistake to repay the assets to her HSA. contact the HSA's again and tell them the money returned was a mistaken distribution to see if they'll issue corrected forms.
however, the IRS also says
Must we report the mistaken distribution to the IRS?
No, according to the Instructions for Forms 1099-SA and 5498-SA, if you choose to accept mistaken distributions, do not report the distribution amount on Form 1099-SA or the recontributed amount on Form 5498-SA. If you did report the mistaken distribution, you should file a correction as soon as the error is discovered.
