If you do not know then do not enter any amounts.  You are not required to enter medical expenses on your tax return, they are all itemized deductions.

Well you have to figure that out somehow.  But it might not be necessary.  You don't need to enter all your deductions if you take the Standard Deduction.  And if you itemize you can only deduct the amount of unreimbursed Medical Expenses you actually paid over 7.5% of your AGI. So it might take a lot to be worth entering.
