What do I do if we haven't received our 1099-SA? Also question about including HSA in medical expenses.

As of Feb. 8, no 1099-SA has arrived. When I went looking for information, I saw a question that had been answered by a TTax person that said, "This is because TurboTax assumes that you are entering all your medical bills (even the reimbursed ones), and then TurboTax subtracts the insurance reimbursement and the HSA reimbursement (distributions)."   I didn't add them to my complete medical expenses because I know they aren't deductible, which makes me wonder if I was s****ed over last year because I didn't.  If I don't receive the form, can I simply add up from my HSA statements what was spent from it, and do I need to enter any HSA distributions with complete medical expenses if TTax is just going to take them back out?
