Did you read that article I linked?

"because the husband has family retiree medical"

If that is employer-paid, it doesn't get included for self-employed health, because the sole proprietor isn't paying. The Medicare premiums count.

"Then maybe only the wife's long term care premiums? Can anyone help with this?"

Yes and the IRS and this article provide limit info:

"If long-term care plans are established under the taxpayer's or spouse's business, and long-term care premiums were paid for persons other than the taxpayer or spouse, manually limit the premiums paid for the other person(s) based on age, per IRS Pub 525, and include the amount in this input field."

Did you read Pub 525? Instructions for Form 7206?
