What type of insurance plan is ours? We both have medicare supplement plans with USAA. I paid 2355. and Glenn paid 2732. in 2016. How do I show that?

The medical expense deduction has to meet a rather large threshold before it can affect your return. The amount of medical expenses that will count toward itemization for someone under 65 is the amount that is OVER 10% of your adjusted gross income; for someone 65 or older it would be the amount over 7.5% of your AGI.  

You should only enter the amount that you paid in 2016—do not include any amounts that were covered by insurance or that are still outstanding.  Of course, your medical expenses plus your other itemized deductions still have to exceed your standard deduction before you will see a difference in your tax due or refund.

To enter your medical expenses go to Federal>Deductions and Credits>Medical>Medical Expenses

Note:  If you are paying your Medicare premiums from your Social Security benefits, the amount taken out of your SS flows automatically to the Medical Expense section of TurboTax when you enter your SSA1099.  You do need to enter your supplemental premiums as medical expenses.  As SweetieJean mentioned, you really do not have to worry about what "category" to enter them into under Medical, as long as you enter them.  TurboTax will calculate whether you are able to get the medical expense deduction.

Medicare supplemental health insurance premiums paid with out of pocket funds and not reimbursed are entered on Form 1040 Schedule A as a Medical expense itemized deduction.

However, only your total medical expenses that are greater than 10% of your Adjusted Gross Income (AGI) can be deducted if you are under age 65.  If you are age 65 or older the AGI limit is 7.5%.  Your total itemized deductions reported on Form 1040 Schedule A must be greater than the standard deduction for your filing status to have any tax benefit.

Standard deductions for 2016 

• Single - $6,300 add $1,550 if age 65 or older
• Married Filing Separately - $6,300 add $1,250 if age 65 or older
• Married Filing Jointly - $12,600 add $1,250 for each spouse age 65 or older

State deductibility may be different.

Our medicare supplement plan from USAA does not seem to fit anywhere in the deductibles.  No matter what I answer, the form says okay, we're done here.  Continue.  I know there must be a place to show the $5000+ we paid in health insurance.  Called USAA and the woman said its not any of the listed things, its just a medicare supplement.  Help!!

If you are referring to the Health Insurance section of the program, you do not enter any type of Medicare supplemental policy in that section.  What is being presented is a list of uncommon plans which you would not be using since you are on Medicare.  Medicare is classified as "minimum essential coverage" under the Affordable Care Act (ACA).  Just answer NO to the question concerning the uncommon plans and Continue.  That will complete the Health Insurance section of the program.
Use the procedure I gave in the Answer above to report the premiums paid for the supplemental insurance.

The Medical expense categories in TT are just for your use, so any one will do (say, Medical Ins Premiums)  will do. Only the total ends up on Schedule A.
