Even if the Taxpayer has the A and the Spouse has the B?  I'm trying to help someone out that did there taxes on Turbo Tax and got a letter from the IRS.

B just informs the world that there was health insurance.  A has all of the juicy information for credits or lack thereof.

So then act as if they both have an A and don't even bother with the B?

If they both had health insurance all year, check the box they had insurance all year.  Then just enter the 1095-A (if column B of the 1095-A is blank, be sure to lookup and enter the proper amount ... actually you may want to look that up anyways:  https://www.healthcare.gov/tax-tool/#/).

The only thing a 1095-B potentially does is tell you if the taxpayer did NOT have insurance all year.  In that case, you need to tell ProSeries which months were not insured.  Otherwise, there is nothing that needs to be done with a 1095-B.
