Deductions & credits

I am doing my daughter's taxes.  She has an HSA.  There is an entry on her W2.  She used her debit card associated with the HSA for medical expenses.  She did not receive a 1099-SA.  From everything I've read, these expenses are distributions but maybe I'm wrong.  Her HSA agency said she didn't get one because she didn't file any manual claims.  I've spent the better part of the day on this mystery.  Any help would be welcome.
