If you took a deduction for your long term care premiums as a medical expense in previous years (Schedule A itemized deductions), you need to report it as a "reimbursed deduction from a prior year". If you did not take the deduction, it is not taxable income.
Here is how to enter it to line 21 in TurboTax:
Under Wages & Income tab:
- On Your Income screen, scroll way down below All Income to Less
Common Income open the menu (if you don't see All Income, click on Add more income first and you will see it)
- Click
on Start next to Miscellaneous Income at the bottom,
- Choose Reimbursed deductions from a prior year
- Check the box next to Medical Expenses
