To enter your LTC premiums and out of pocket medical/dental and prescription expenses (all in the same section):

1. Sign in to TurboTax. On the first screen (Tax Home), select: Take me to my return.
2. Search for "Schedule A" and then select Jump to Schedule A in the search results.
3. You'll be taken to the Medical Expenses screen. Answer Yes.
4. As you proceed through the medical expenses section, make sure you go past the Long-term care services screen. This screen is for actual care expenses, not insurance premiums.
5. When you reach the Insurance Premiums screen, enter your gross (total) long-term care premiums.
