This is available in TurboTax Desktop and you can use the following steps. It must be entered using the steps below.
Here's how to enter your 1099-LTC into TurboTax (Step-by-Step vs Search):
Following those links, I come to the 1099-LTC section. My form has "Reimbursement amount" checked in Box 3, it does not have "Per diem" checked. When I go through the screens, there is nowhere to enter the amount in Box 1 "Gross long-term care benefits paid". Is that correct?
Not quite. Keep going through the screens until you see one that asks about Long-Term Care costs. There will be a place to enter a number of days of care, the total cost of the care received, and the reimbursements you received. The reimbursements would be the amount reported in box 1 of your 1099-LTC.
My 1099-LTC does not have an entry for a number of days or the total cost of care received, only a Box 1 Gross long-term care benefits paid. Box 3 only has "Reimbursement amount" checked, not per diem.
If I use information from my records on number of days and total cost, it tells me the amounts are not taxable. Should I be using my records for this information?
EDIT: Reading the instructions to Form 8853 (the form TT is using), if the payment is not "Per diem" (as defined) and not a death benefit, then 8853 should not be filled out. The TT instructions should be fixed to make this clear.
