I made excess contribution withdraws from my HSA for contributions for 2018, but my HSA administrator processed it for 2019. They say they can't correcit it Is this okay?

They said that it won't matter that they can't give a corrected 5498-SA for 2018, but the 1099 sa for 2019 will show the withdraw and this should make the IRS happy. I'm just worried that because the 5498 shows the wrong amount and could cause an audit for 2018. Will this be okay with the IRS?
