I had same problem. Using purchased TurboTax Premier
The other posted answer to just let it stay under wrong name bothered me. Found a fix.
From Step by Step page where you enter details of the 1095-A (heading "Let's get the info from your 1095-A form") click on the upper right FORMS icon to bring up the actual form. It is headed " Health Insurance Marketplace Statement". On that I found boxes below the names that let you pick taxpayer or spouse. When I clicked the Spouse box, name, social and birthday auto filled.
However, it did NOT automatically fix the Med Wks "Schedule A Medical Worksheet". I needed to pull up that form and manually type in the spouse portion amount in the detail for line 2b. Once the spouse amt put in, the taxpayer portion did auto fill to the correct amount.
